What Is a Jockey Wheel? A Thorough Guide to Understanding the Essential Trailer Accessory
Whether you own a caravan, a trailer, or a towable load that sits on a drawbar, the jockey wheel is one of the most practical components you’ll encounter. It’s the small wheel at the end of the stand that makes hitching, manoeuvring, and stabilising your trailer far easier. For many, the question “what is a jockey wheel?” is the first step towards a safer, smoother towing experience. In this guide, we unpack the purpose, parts, different types, and practical tips you’ll need to know so you can choose, use and maintain your jockey wheel with confidence.
What Is a Jockey Wheel? A Simple Definition
What is a jockey wheel in practical terms? It is a collapsible, adjustable stand with a wheel designed to support the front end of a trailer or caravan when it is not connected to a towing vehicle. When the trailer is detached, the jockey wheel bears some of the weight, allowing you to steer, level and move the trailer by hand. The wheel itself acts like a tiny, mobile support leg that can be lowered to the ground or raised up and out of the way when it is not needed.
Key Roles of a Jockey Wheel
- Support and stability when the caravan is unhitched from the tow car.
- Assistance with manoeuvring the trailer around the site, especially on uneven ground.
- Easing the process of hitching and unhitching by providing a stable, adjustable point of contact.
How a Jockey Wheel Works
Understanding how a jockey wheel functions helps you use it correctly and avoid damage or injury. The device consists of a vertical leg with an adjustable height mechanism, a wheel at the base, and a clamp or mounting collar that attaches to the drawbar of your trailer or caravan. Some models incorporate a swivel mechanism at the top of the leg, which allows the wheel to rotate when you push or pull the trailer, making steering easier.
Adjusting the Height
The height of the jockey wheel is typically adjusted using a screw thread, a crank handle, or a quick-release system. When you lower the wheel to the ground, you are creating a stable support point. When you raise it, you clear the ground so you can hitch or move the trailer without interference. It is crucial to set the height so that the hitch ball aligns with the tow vehicle’s hitch socket and the front of the caravan sits level or has the intended tilt for proper towing.
Swivel vs Fixed Jockey Wheels
Some jockey wheels swivel at the base, allowing the wheel to turn with the trailer during movement. This makes pushing or moving the trailer easier and reduces the risk of scraping or catching on obstacles. Fixed jockey wheels lack this swivel capability and can be more stable in a straight-line pull, but require more effort to steer around corners or obstacles.
Types of Jockey Wheels
There are several varieties of jockey wheels, each with distinct advantages depending on your trailer, terrain and how frequently you hitch and unhitch. Here are the main types you’re likely to encounter.
Manual Crank Jockey Wheels
These are the traditional options you’ll see on many caravans. A hand crank or handle is used to screw the wheel up and down. They’re straightforward, robust and inexpensive, making them a popular choice for many users.
Wheel Sizes and Materials
Jockey wheels come in different wheel diameters, commonly 150mm or 200mm. Larger wheels can roll more smoothly over rough ground and are less prone to getting bogged down in soft surfaces. The wheel material is usually steel with a painted finish or a zinc coating to resist corrosion. Some wheels are made from polymer composites or rubber for lighter weight and reduced rolling resistance.
Swivel vs Non-Swivel Heads
Swivel heads make it easier to steer the trailer while moving it on the drawbar, especially when you’re navigating around a campsite or driveway. Non-swivel heads are typically more rigid and can handle heavier loads with less wobble on long straight pulls.
Height-Adjustable vs Fixed Length
Most jockey wheels offer a range of height adjustments to accommodate different towing vehicles and load configurations. A fixed-length design may be simpler and more compact, but a height-adjustable model provides greater versatility, especially if you tow different trailers or travel on varied terrains.
When to Use a Jockey Wheel
The primary purpose is to support the front of the trailer when it is not connected to the tow vehicle. You’ll typically use a jockey wheel in the following situations:
- During hitching and unhitching to keep the trailer from dropping or lifting erratically.
- When manoeuvring or repositioning a stationary trailer on a campsite or driveway.
- To stabilise the trailer after uncoupling, helping to balance the load and reduce sway during short-term parking.
Practical Scenarios
On uneven ground, the jockey wheel helps level the caravan or trailer enough to couple to the vehicle or to prepare the site for stabilisation jacks. In windy conditions, a well-set jockey wheel reduces the risk of sudden movement as you hitch or unhitch.
How to Choose the Right Jockey Wheel
Choosing the right jockey wheel is about balancing weight capacity, ease of use, terrain compatibility and budget. Here are the main considerations to guide your decision:
Weight Capacity and Load Rating
Check the load rating of the jockey wheel to ensure it can comfortably support the front end of your trailer when unhitched. If the wheel is underspecified, it can slip, buckle or fail under load, which could lead to damage or injury. Multiply the weight of the front of your caravan or trailer by a safety factor (usually around 1.25 to 1.5) to determine the minimum rating you should consider.
Wheel Diameter and Tread
A larger wheel generally performs better on rough ground and soft surfaces. If you frequently park on grass or muddy sites, a bigger wheel with a more rugged tread will provide better stability and reduce the effort required to move the trailer.
Mounting Compatibility
Ensure the jockey wheel’s mounting collar matches your drawbar’s size and the clamp mechanism is compatible with your caravan or trailer. Some drawbars use a specific thread or bolting pattern; verify this before purchasing to avoid compatibility issues.
Swivel Mechanism and Ease of Use
Consider whether you want a swivel head for easier steering or a fixed head for simplicity and durability. If you tow in variable terrain or frequently need to reposition on site, a swivel head can be a real asset.
Build Quality and Materials
Steel jockey wheels offer excellent durability but may be heavier and more prone to corrosion if not galvanised. Aluminium options are lighter and resist corrosion well but can be pricier. For coastal sites or frequent exposure to salt air, corrosion resistance is an important factor.
Maintenance and Serviceability
Some models are easier to service than others. Look for wheels with readily replaceable bearings, simple lubrication points and a robust locking mechanism for height adjustment. If you travel widely, a model with readily available spares is worth considering.
Installation and Safe Use: A Step-by-Step Guide
Getting the installation right is essential for safe towing and easy operation. Here is a straightforward approach to installing and using a jockey wheel safely.
Step-by-Step Installation
- Park the trailer on firm, level ground and engage any stabilisers or wheel chocks as needed.
- Position the jockey wheel at the front end of the drawbar, aligning the mounting collar with the drawbar diameter and the clamp holes (if applicable).
- Lower the leg with the wheel until the wheel touches the ground and the front of the trailer is supported, but not bearing all the load. Ensure the trailer remains level to avoid pitching when hitching.
- Secure the jockey wheel with any locking bolts or clamps according to the manufacturer’s instructions. Ensure the mechanism is fully engaged before applying load.
- Adjust the height so that the hitch aligns with the tow car’s hitch ball. The trailer should sit slightly level or with the manufacturer-specified pitch for safe towing.
Tips for Safe Use
- Never rely on the jockey wheel alone to bear the full weight of the front end when loading or hitching. Use wheel chocks and stabilisers as needed.
- Never stand in line with the jockey wheel when lowering or raising it; be mindful of pinch points and potential hand injuries.
- When moving the trailer, keep a clear path and go slowly. A swivel jockey wheel aids steering, but unexpected obstacles can still cause damage.
- After hitching, re-check the height and alignment to ensure the tow bar is correctly positioned before you start driving.
Maintenance and Care
Regular maintenance extends the life of a jockey wheel and keeps it functioning reliably. Here are practical care tips you can incorporate into your routine.
Lubrication and Wear Checks
Lubricate the screw thread, swivel head (if present), and any moving joints with a light grease or penetrating oil at regular intervals. Check for worn bearings, cracks in the wheel, or play in the leg. If you notice significant wear or looseness, replace components or the entire unit as needed.
Cleaning and Protection
Rinse off mud and debris after use, especially in coastal or muddy sites. Dry thoroughly and apply a thin coat of protective oil to metal surfaces to prevent rust. If you store the trailer for extended periods, consider covering the jockey wheel or storing it indoors to reduce exposure to the elements.
Storage Considerations
Store the jockey wheel in a dry area away from direct sunlight when not in use. Avoid exposing plastic components to extreme temperatures, which can cause cracking or deformation over time.
Common Problems and Troubleshooting
Even well-made jockey wheels can experience occasional issues. Here are common symptoms and practical fixes.
Wobble or Play in the Leg
This can indicate worn pivot points, loose clamps or damaged bearings. Tighten clamps if possible, and inspect the leg for bends or fracture. If the wobble persists, it is prudent to replace the affected component or the entire unit.
Wheel Not Turning Freely
Grit, rust or dried lubrication can hinder the wheel’s rotation. Clean the wheel hub and apply appropriate lubrication. If the wheel is seized due to corrosion, a replacement may be necessary.
Height Adjustment Stiffness
Stiff screw threads can be caused by dirt or corrosion. Apply a lubricant along the thread, move the wheel up and down to work the lubricant in, and wipe away excess. If the thread remains stiff, the unit may require servicing or replacement.
Clamp or Lock Slippage
Clamps that do not hold firmly can lead to the jockey wheel dropping during hitching. Inspect the locking mechanism for wear, replace damaged parts, and ensure the clamp is tightened to the manufacturer’s specification.
Safety Considerations
Safety is an ongoing concern when dealing with any towing equipment. The jockey wheel is a small but crucial part of the system that supports a heavy load.
Best Practices for Safe Use
- Always apply wheel chocks when the trailer is detached to prevent movement.
- Don’t stand directly in front of or behind the wheel while adjusting height; keep hands clear of pinch points.
- Ensure the ground is solid and level before placing the jockey wheel down. Soft ground can cause the leg to sink, compromising stability.
- Check the entire hitch assembly after adjustments to confirm that nothing has shifted during handling.
