Drop beam axles provide a lower ride height than a straight or overlay beam axle. Using a drop plate, the stub axle and axle shaft are welded onto either side, allowing for a lower height. These are typically used for race car trailers and horse floats where lower heights are required for easier entry and exit. Here at Sunrise we proivde 2" and 4" drop axles. One of the key components that can make a big difference in the way your caravan handles and performs is the drop axle. In this post, we'll take a look at what drop axles are, how they work, and how they can improve the performance of your caravan. What are Drop Axles? Drop axles are a type of suspension component that are designed to lower the center of gravity of an caravan. This can be beneficial for several reasons, including improved handling and stability, as well as increased towing capacity. The way that drop axles work is by lowering the entire axle assembly, which includes the wheels and tires. This can be done by either shortening the axle itself, or by attaching it to the frame at a different point. The Benefits of Drop Axles for Caravans Improved handling and stability: Lowering the center of gravity of the trailer makes it less likely to roll or tip over in windy conditions or when making sharp turns. Increased towing capacity: Lowering the axles can help distribute the weight of the trailer more evenly, which can prevent the axles from becoming overloaded. Better clearance: Drop axles can provide more clearance for the trailer, which can be especially useful for trailers that will be traveling on rough or off-road terrain. Enhanced aesthetics: Drop axles can also improve the overall appearance of the trailer, making it look sleeker and more streamlined. Better suspension: Drop axles can also improve the suspension of the trailer, which can help absorb bumps and vibrations on the road. Increase the lifespan of the tires: Drop axles can also reduce the wear and tear on the tires of the trailer, which can increase the lifespan of the tires. How to Choose the Right Drop Axles for Your Caravan When it comes to choosing drop axles for your caravan, there are a few things to keep in mind. First, you'll want to make sure that the drop axles you choose are compatible with your caravans make and model. This will ensure that they fit properly and work as intended. You can contact our friendly staff to help you with working out what size you need. Next, consider the load capacity of the drop axles you're interested in. Make sure that they can support the weight of your caravan and any additional loads you plan to carry. Overall, drop axles can be a great way to improve the performance and appearance of your caravan. By lowering the center of gravity and distributing weight more evenly, they can help to improve handling, stability, and towing capacity. When choosing drop axles for your caravan, be sure to consider compatibility, load capacity, and overall appearance."  

Bearings are commonly used in trailer parts such as between your brake drum, discs or hubs. They consist of two parts, the cup and the cone, which are pressed into the hub to aid smooth, rolling rotation for your wheels during towing. In each hub, there are two pairs of bearings, one for the outer and one for the inner, both of which have one cup and one cone. The outer bearings pair (closest to the curb) are the smallest and the inner bearing pair (closest to the trailer) are the larger bearings. The inner bearings are matched with an oil/grease seal to perfectly fit and prevent lubricants from escaping the bearings. In each hub, there are two pairs of bearings, one for the outer and one for the inner, which each have one cup and one cone. When building or repairing a trailer, bearings can be a complex part to break down. Using the table below, we’ve provided a chart which provides information to find out which bearings you need. It includes bearing numbers, the OD (outer diameter) and ID (inner diameter) as well as the width, which should make finding the part you need as easy as possible. How to Check What Bearings I Need? If you're looking to find the trailer bearing numbers on your trailer, there are a few different ways to go about it. Here are a few tips to help you locate the information you need: Check the owner's manual: Many trailers come with an owner's manual that includes information about the bearings. If you still have the manual, it's worth checking to see if the bearing numbers are listed. Look for a label or sticker: Many trailers have a label or sticker on them that includes the bearing numbers. This label or sticker may be located on the axles or on the frame of the trailer. Inspect the bearings: If you can't find the bearing numbers through the above methods, you may need to inspect the bearings themselves. The bearing numbers are typically stamped on the bearings. Contact the manufacturer: If you're still having trouble finding the bearing numbers, you can contact the manufacturer of your trailer. They should be able to provide you with the information you need. Use online resources: Lastly, you can try searching online for resources that can help you find the bearing numbers on your trailer. There are many forums, FAQ sections, and online guides available that can help you find the information you need. The Importance of Bearing Maintenance Let's discuss the importance of regular maintenance for trailer bearings. Trailer bearings should be inspected and lubricated at least once a year, or more frequently if you use your trailer frequently or for long distances. This can be done by a professional mechanic or by yourself, with the right tools and knowledge. When inspecting your trailer bearings, look for signs of wear and tear such as discoloration, rust, or damage to the seals. If you notice any of these issues, it's time to replace the bearings. It's also important to note that if you experience issues with vibration or noise while towing your trailer, this could be a sign that your bearings need to be replaced. Picking The Right Bearings When it comes to choosing the right bearings for your trailer, there are a few factors to consider. The first thing to consider is the size and weight of your trailer. The bearings that are suitable for a small utility trailer may not be suitable for a large horse trailer. It's also important to consider the type of terrain and weather conditions your trailer will be exposed to, as this can affect the durability of the bearings. Another important factor to consider when choosing trailer bearings is the quality of the bearings. It's important to choose bearings from a reputable manufacturer that are known for their durability and quality. Avoid buying low-quality bearings as they may not last as long and can cause more damage to your trailer in the long run.

Whether you're towing for the first time or you're an experienced tower, you may have some questions or doubts on the requirements of having compliant safety trailer chains. The team at Sunrise are here to help make sure you have the right answers to meet legal requirements. The Legal Requirements of Safety Chains Safety chains are mandatory throughout Australia. They serve to maintain the connection between a trailer and its towing vehicle should there be any coupling failure. The first step in finding the right chain is to understand the term Aggregate Trailer Mass (ATM). The ATM is the total weight of a trailer and its maximum (or full) load when NOT coupled to a vehicle. This figure is commonly stamped onto the trailer VIN plate. Safety chains must be marked in accordance to the relevant Australian Standard and your trailer ATM. Australian Standard for Safety Chains Safety chains are an important component of trailer safety in Australia and must comply with Australian Standards AS 4177.4-1994 or AS 4177.4-2004. These standards outline the requirements for safety chains on trailers and other vehicles that are used for towing. Where Should I Attach Safety Chains? According to these standards, safety chains must be attached to the tow vehicle and the trailer in a way that prevents the trailer from becoming detached in the event of a failure of the tow hitch or other connection. Safety chains must be of a suitable size, strength, and design to prevent the trailer from separating from the tow vehicle. The safety chains must be attached to the tow vehicle and the trailer in such a way that they are taut when the trailer is connected to the tow vehicle, but not so tight that they impede the movement of the trailer. They must also be easily accessible for inspection and maintenance. It's also important to note that safety chains must be visible and not obscured by any other equipment or parts of the trailer or tow vehicle. Where Can i Purchase Safety Chains Sunrise has an extensive range of safety chains. You can view all our safety chains here. What Rating is Required for Safety Chains on Trailers? The standard also specifies the minimum breaking strength of the safety chains, which is typically around 2.5 times the Gross Trailer Mass (GTM) of the trailer. It also specifies the minimum number of safety chains that must be used, which is typically two. Your trailer ATM will help to determine which safety chain you will need. See the guide below to help you find your suitable safety chain: ATM less than or equal to 2.5T If your trailer ATM does not exceed 2.5 tonnes, you must have at least one safety chain complying and stamped with Australian Standard AS 4177.4-1994 or Australian Standard AS 4177.4-2004 “Caravan and light trailer towing components, Part 4: Safety chains up to 3500 kg capacity”. 2.5T < ATM ≤ 3.5T If your trailer ATM is over 2.5 tonnes but does NOT exceed 3.5 tonnes, you must have two safety chains complying and stamped with Australian Standard AS 4177.4-1994 or Australian Standard AS 4177.4-2004 “Caravan and light trailer towing components, Part 4: Safety chains up to 3500 kg capacity”. ATM > 3.5T If your trailer ATM is over 3.5 tonnes, the safety chain must be permanently attached to the trailer; shackles are not permitted. The safety chain must not be welded to the draw bar. Alternatively, a plate welded to the draw bar, or an appropriate device like the Hammerlock Hook may be used. You must have two safety chains made of steel. They must have a minimum 800 MPa breaking stress that conforms to the mechanical properties of Grade T chain. This is specified in Australian Standards AS 2321-1979 “Short Link Chain for Lifting Purposes (Non Calibrated)“. Alternatively, safety cables with equal capacity to the relevant safety chains may be used on towing vehicles with ATM up to 3.5T.   Note: Any trailer without breakaway brakes must be fitted with safety chains that are marked in accordance with relevant Australian standards depending on your trailer ATM. Contact your local Sunrise store for more information on your trailer safety chains and trailer ATM. We are always happy to help, visit us in store where a team member can assist with any enquiries you may have.

Straight beam axles are the most classic and common type of axles. Typically used on domestic trailers, utility trailers, boat trailers and more.

Trailer axles are a crucial component of any trailer, responsible for supporting the weight of the cargo and providing stability while in motion. Among the different types of axles available, lazy non-braked axles are a popular choice for many trailer owners. In this post, we'll take a closer look at lazy non-braked axles, what sets them apart from other types of axles, and how to properly maintain them. What Are Lazy Non Braked Axles? Lazy non-braked axles, also known as idler axles, are a type of trailer axle that is not connected to the braking system of the vehicle. Unlike other types of axles, such as live or braked axles, lazy non-braked axles do not provide any braking force to the trailer. Instead, they are used as a support system for the weight of the cargo, and are typically found in the middle of a dual-axle trailer setup. Advantages of Lazy Axle Set ups? The main advantage of lazy non-braked axles is their simplicity. Without the need for braking components, these axles are generally easier and less expensive to maintain. Additionally, lazy non-braked axles can be a good choice for trailers that are carrying lightweight cargo, as they are not designed to provide braking force and may not be necessary. However, there are a few important things to keep in mind when it comes to maintaining lazy non-braked axles. It is essential to regularly check the wheel bearings and make sure they are properly lubricated to prevent wear and tear. Additionally, the tires should be properly inflated and in good condition to ensure maximum performance and safety. How do Lazy Axles Compare to Other Trailer Axles? Lazy axles differ from other types of trailer axles, such as live or braked axles, as they are not connected to the braking system of the vehicle. This means they are not designed to provide braking force, but instead are used as a support system for the weight of the cargo. Lazy axles are generally simpler and less expensive to maintain compared to other trailer axles. However, it is important to regularly check the wheel bearings and properly inflate the tires for optimal performance and safety. Things to Shoulder When Selecting an Axle When it comes to selecting the best axle for your trailer, there are several factors to consider. The first thing to consider is the weight of your cargo. Heavy loads will require stronger and more durable axles, such as live axles or braked axles. If you plan to frequently transport lightweight cargo, lazy or idler axles may be a better option as they are simpler and less expensive to maintain. Another important factor to consider is the type of terrain you will be traveling on. Off-road conditions may require more robust axles with higher load capacity. Additionally, it is essential to ensure that the chosen axle is compatible with your towing vehicle and comply with the local laws and regulations 1. Load Capacity When selecting an axle for your trailer, it is important to consider the load capacity, which is the maximum weight the axle can support. It should match the Gross Vehicle Mass (GVM) of the trailer. It is advisable to choose an axle with a higher capacity than what is needed. 2. Tyre and Wheel Capacity When considering the type of axle for your trailer, it is important to take into account the capacity of the wheels and tires, as they can greatly impact the choice of axle. Keep in mind that the wheel and tire load capacities should exceed that of the axle. Additionally, factors such as the length, width of the chassis, axle spacing, stud pattern, mounting position, and backspace of the wheel should also be taken into account when making a selection. Lazy axles consist of a straight beam axle with lazy hubs fitted. (To view our available lazy hubs, click here.)  Here at Sunrise, we are committed to helping our customers.

There are two varieties of electric brake magnets. In this guide, we’ll clarify the difference between them and explain why it’s crucial to have off-road magnets installed when navigating corrugated roads. At the end of this article, you’ll also find useful tips and guidance on how to inspect magnet wear and key features to watch for. Standard Electric Brakes vs. Off-Road Electric Brakes Electric trailer brakes are one of the most used brakes on Australian Roads. By law in Australia, you are legally required to install electric brakes on any trailer or caravan weighing over 2000kg (GTM). These brakes must also be fitted with a safety breakaway unit. A breakaway unit is an electrical device that will automatically activate in the event a trailer is accidently separated from the towing vehicle. Essentially if a trailer were to accident dis-connect from the trailer while you are traveling up a hill, the pin will be pull out from the break away switch and this will cause the battery in the breakaway unit to activate and send an electrical signal to the electric brakes on your trailer to turn on. A breakaway unit is designed to only provide power for approximately 15 minutes which should be enough time to re-hook the trailer to the car. In electric trailer brakes, when power is supplied to the trailer backing plate the magnet is attracted to the face of the trailer brake drum. The brake shoes of the backing plate are also push out to the drum. Thus, the friction from the trailer magnet and brake shoes touching the drum is what slows down the trailer. It is due to friction that trailer magnets and brakes shoes require frequently replacement, we suggest checking your trailer brakes every 6 months. A standard trailer magnet wears out much faster due to this frictions, especially in off road conditions, often the retaining clip that holds the magnet can come loose in tough terrain. Hence why the off-road style of electric brake magnets is much better and longer lasting. These are most popularly used by our OEM customers. Upgrading to off-road magnets before your next outback adventure can save you time, money, and the inconvenience of waiting for replacement parts. How Dirt Roads Ruin Electric Brakes It's well-known that dirt roads can damage electric brakes. Many caravan owners are unaware that the vibrations from corrugated roads can cause significant harm to their electric brake systems and drums. We've encountered numerous requests for replacement drums. Upon investigation, we often find the magnet has worn through the steel casing, making the electric magnet unusable. Additionally, the magnet arm tends to suffer damage. Customers often find it more efficient and cost saving  to replace the the entire backing plates and purchase new electric drums. Magnet Retaining Clip One important note: off-road magnets do not come with a retaining clip. Sunrise suggests that you can secure the magnet arm with a rubber band. During your first braking event, the rubber band will break, allowing the magnet to shift into its optimal working position. How to Inspect Magnet Wear Here’s how you can check for magnet wear: Each of our magnets has four small holes on face of the magnet; these holes indicate the level of wear. If you can no longer see these tiny four holes then it’s time to replace the magnet. If the magnet’s face has worn down to reveal copper, your brakes will become inoperable due to an open circuit. Key Features Wear indicator holes are located at 3, 6, 9, and 12 o’clock positions. Each magnet draws approximately 3.2 amps. Wires can be connected as either positive or negative. Once the magnet is worn, copper exposure can lead to brake failure. Where to Purchase Replacement Trailer Electric Brakes Sunrise has a wide range of replacement trailer brake parts for electric brakes, the most commonly parts are. The most commonly size for electric trailer brakes is 10" and 12" internal diameter of the drums used. 10" Electric backing plates in left or right side 10" Eletric Trailer Drums 10" Replacement Magents 10" Electric Brakes Shoes  You can also purchase complete trailer electric brake kits here. TIP: To maximize braking performance, bed in new magnets correctly. Initially, the face of the magnet will have a smooth, shiny finish that needs to be roughened through normal use to achieve full effectiveness. This means it make take a couple of drives before the brakes start operating smoothly.

Understanding Trailer Bearings What are trailer bearings and their function Trailer bearings are crucial components in your trailer's wheel assembly, playing a vital role in ensuring smooth and efficient movement. These small but mighty parts allow the wheels to rotate freely while supporting the weight of the trailer. Bearings reduce friction between the wheel hub and axle, preventing overheating and premature wear. Types of trailer bearings There are two main types of trailer bearings: Roller bearings Ball bearings Type Advantages Best suited for Roller bearings Higher load capacity, better for heavier trailers Large trailers, heavy-duty applications Ball bearings Smoother operation, less friction Smaller trailers, lighter loads Signs of worn-out bearings Recognizing the symptoms of failing bearings is crucial for timely maintenance. Look out for these warning signs: Unusual noises (grinding, squealing, or rumbling) Uneven tire wear Excessive heat from the hub Wheel wobble or vibration Grease leakage on the inside of the tire Regular Inspection: Your First Line of Defense How often to inspect bearings Regular inspection of trailer bearings is crucial for maintaining their longevity and ensuring safe towing. The frequency of inspection depends on several factors: Frequency of use Towing conditions Load weight Manufacturer recommendations Here's a general guideline for inspection intervals: Usage Inspection Frequency Light use Every 3-6 months Moderate use Every 2-3 months Heavy use Monthly After long trips After each trip What to look for during inspection When inspecting your trailer bearings, pay close attention to: Signs of wear or damage Unusual noises or vibrations Excessive heat Grease consistency and color Seal condition Tools needed for inspection To perform a thorough bearing inspection, you'll need: Jack and jack stands Wheel chocks Flashlight Gloves Clean rags Grease gun Bearing packer (optional) Creating an inspection checklist Develop a comprehensive checklist to ensure consistent and thorough inspections: Secure the trailer Jack up the wheel Remove the dust cap Check for play in the wheel Inspect the grease condition Examine the bearings for wear Check the seals for damage Repack with fresh grease if needed Reassemble and adjust By following this inspection routine, you'll catch potential issues early, extending the life of your trailer bearings and ensuring safer towing experiences. Remember, if you're unsure about any aspect of the inspection process, it's always best to consult a professional mechanic. Proper Cleaning Techniques A. Removing old grease and debris To effectively clean your trailer bearings, start by carefully removing all old grease and debris. This process is crucial for ensuring optimal performance and longevity. Begin by using a clean cloth or paper towel to wipe away excess grease. For stubborn residue, employ a putty knife or scraper, being cautious not to damage the bearing surfaces. B. Cleaning solutions and methods Once the bulk of the old grease is removed, it's time to employ cleaning solutions. Here's a comparison of common cleaning methods: Method Pros Cons Solvent bath Thorough cleaning, removes all residue Requires proper disposal, can be harsh Soap and water Eco-friendly, readily available May not remove all grease, risk of rusting Specialized bearing cleaner Designed for bearings, effective More expensive, may require special handling Regardless of the method chosen, ensure thorough cleaning of all bearing components, including the races and cages. C. Drying and preparing for re-lubrication After cleaning, proper drying is essential to prevent rust and ensure effective re-lubrication. Follow these steps: Use compressed air to blow out any remaining cleaning solution Wipe down all components with a clean, lint-free cloth Allow bearings to air dry completely in a dust-free environment Inspect bearings for any signs of wear or damage before re-lubrication With your bearings now clean and dry, they're ready for the next crucial step in maintenance: proper lubrication. This process will ensure smooth operation and protect against wear and corrosion.

Wiring the lights on your trailer in Australia is not only important for safety, but it is also a legal requirement. In this blog post, we will discuss the different types of trailer light wiring in Australia, the tools and materials you'll need, and tips for troubleshooting common wiring issues. What Lighting do I Need on my Trailer? The Australian Design Rules (ADR) regulates the lighting and markings for all types of vehicles, including trailers. According to ADR, trailer lights must include a brake light, a tail light, a license plate light, and a side marker light, as well as an indicator light for each direction of travel. The most common type of trailer light wiring in Australia is the 7-pin flat system. This system includes the basic lights such as tail lights, brake lights, and turn signals, as well as a center pin for the electric brakes. It also includes a pin for a reverse light, which is mandatory to have in Australia. How to Wire a Trailer Plug Gather the necessary tools and materials: You will need a 7-pin flat trailer plug, a trailer wiring harness, a crimping tool, wire cutters, and electrical tape. Locate the wiring harness on your vehicle: The wiring harness for the trailer plug is typically located near the rear of the vehicle. Consult the vehicle's owner manual for the exact location. Cut the wiring harness: Using wire cutters, cut the wiring harness to the appropriate length to reach the trailer plug. Crimp the wires: Use the crimping tool to attach the wires from the wiring harness to the corresponding pins on the trailer plug. Make sure to match the correct wire colors to the correct pins. Test the lights: Once the wiring is complete, test the lights on the trailer to ensure they are functioning properly. Secure the connections: Use electrical tape to secure all connections and to protect them from the elements. To wire the lights on your trailer, you will need a 7-pin flat trailer plug, a trailer wiring harness, and the appropriate wiring diagram for your vehicle. You will also need basic tools such as wire cutters, crimpers, and electrical tape. When wiring your trailer lights, it's essential to ensure that all connections are clean and secure. Loose connections can cause the lights to malfunction or not work at all. Also, it's important to make sure that the wiring is correctly color-coded according to the ADR standards, as incorrect color-coding can lead to dangerous situations on the road. If you experience any issues with your trailer lights, the first step is to check the connections to ensure they are clean and secure. If the problem persists, you can check the wiring diagram for your vehicle and trailer to see if you've made any mistakes. Another common issue is a blown fuse, so make sure to check that as well. The Importance of Connections Trailer plugs are an essential connecter between your car and any additional unpowered towing vehicle. Anything from a trailer, caravan, campervan, boat trailer to a horsebox. All objects in tow must have a plug connection to be inserted into the socket of your car. This electrical link ensures all lights, brakes and any additional attachments receive power. Basic lighting connections include the left-hand indicator, right hand indicator, brake lights, taillights and side lights. Trying to constantly monitor your trailer lights while driving is not practical, therefore having the correct connections is vital for safe, secure towing and peace of mind. Connectors are a mandatory component on any trailer in Australia, with standardized colours on all core wiring. The most commonly used is the 7 pin plugs. These are available flat or round, the latter available in the large type 1 connector with a 20mm PCD or the small Type 2 connector with a 13mm PCD.

Finding the right stud pattern for your vehicle's wheels can be a tricky task, but with the right knowledge and tools, it can be done with ease. In this blog post, we'll go over everything you need to know about stud patterns, including how to find the stud pattern for your vehicle and what to look for when selecting new wheels. What is a Stud Pattern? First, let's start with the basics. A stud pattern, also known as a bolt pattern, is the arrangement of the holes on a wheel that the studs on your vehicle's hub go through. The stud pattern is measured in a number of holes and the diameter of the circle that they form. For example, a 5x114.3 stud pattern would have 5 holes arranged in a 114.3mm diameter circle. How Do I Find the Stud Pattern of My Wheel? 1.  Look at the Owner's Manual To find the stud pattern for your vehicle, you can start by checking the owner's manual. This should include information on the vehicle's stud pattern, as well as other important wheel and tire specifications. If you don't have the owner's manual, you can also check the door jamb or the vehicle's VIN number for information on the stud pattern. 2. Measure it Directly Another way to find your vehicle's stud pattern is to measure it directly. To do this, you'll need a stud pattern gauge, which is a tool that allows you to measure the distance between the center of each stud hole. This can be purchased online or at a local auto parts store. Once you know your vehicle's stud pattern, you can start looking for new wheels that will fit. When selecting new wheels, it's important to ensure that the stud pattern of the wheels matches that of your vehicle. Additionally, you should also make sure that the wheel's center bore and offset are compatible with your vehicle. When it comes to stud patterns, it's important to remember that not all wheels will fit all vehicles. That's why it's essential to know your vehicle's stud pattern and to select wheels that are compatible. By following these tips, you can find the perfect stud pattern for your vehicle and get the best fit for your new wheels. More on Stud Patterns Stud patterns, also commonly known as bolt patterns, bolt circles, lug patterns or PCD’s (pitch circle diameter) – nevertheless, stud patterns are determined by the diameter of a circle which runs through the centre of a wheels stud holes. Generally, there are 4, 5 or 6 stud holes. This diameter determines your stud pattern, which using the table below, will help provide you important information on your wheel set up such as the stud distance and most commonly used wheel stud size. “…stud patterns are determined by the diameter of a circle which runs through the centre of a wheels stud holes”   Odd and Even Stud Pattern Measurement Methods When it comes to finding the correct fittings for your axles, it is important to know your required stud pattern to match the wheel pattern. For uneven stud holes such as 5 stud patterns, measure from the centre of one stud, to the furthest edge of the most opposite stud. For even stud holes such as 4 or 6 stud patterns, simply measure from the centre of one stud, to the centre of the opposite stud. Compare your measurements to the stud PCD column in the table below to find your stud pattern. Here at Sunrise, we are always happy to lend a helping hand to our customers – if you require more information, or want to be sure about your measurements, contact your local Sunrise store or bring in your wheel and we can help you on the spot.
