Your jockey wheel does its hardest work in the worst conditions: hitched and unhitched in mud, dragged across gravel, splashed by road salt, and loaded with hundreds of pounds of trailer nose weight. Yet it is one of the most neglected components on any caravan or camper trailer. An ARK jockey wheel is built to take abuse, but even the best hardware seizes, rusts, and wears out if you never touch it. An hour of annual maintenance keeps it spinning smoothly, prevents the gearbox from grinding itself to death, and saves you from the frustration of a frozen wheel when you are trying to level your trailer on a slope. This guide walks you through a complete annual service step by step.
Step 1: Inspect Before You Touch Anything
Start with a clean visual inspection before you disassemble anything. With the jockey wheel off the trailer or with the trailer safely chocked and supported, look over the whole unit. Check the outer tube and inner shaft for dents, bending, or deep corrosion. A bent inner shaft will bind no matter how much grease you add, and it is the number one cause of a handle that suddenly becomes hard to turn.
Spin the wheel by hand and listen. A smooth, quiet rotation is what you want. Grinding, clicking, or a wobble means the wheel bearing or the swivel needs attention. Turn the handle through its full travel and feel for rough spots or play in the gearbox. Inspect the tyre or solid wheel for flat spots, splits, and tread wear, and check that the clamp bracket bolts are present and tight. Note anything that feels off so you know where to focus during the service.
Step 2: Clean Off the Season's Grime
Maintenance grease is useless if you trap dirt under it. Wipe down the entire jockey wheel with a rag, then use a stiff brush to knock loose the caked mud, grit, and old grease around the gearbox housing and the inner shaft. For heavy build-up, a degreaser spray and a wash will get into the threads and around the wheel hub.
Pay special attention to the inner shaft. Extend it fully and clean the entire length, because this is the surface that slides up and down inside the outer tube every time you wind the trailer up or down. Any grit left on the shaft acts like sandpaper and scores the tube. Dry everything thoroughly before you move on. Trapping water under fresh grease is a fast route to internal rust.
Step 3: Grease the Shaft, Gearbox, and Bearings
This is the heart of the service. Apply a quality marine or lithium-based grease, which resists water washout far better than general-purpose grease, to the full length of the clean inner shaft. Wind the handle to draw the shaft fully in and out a few times to work the grease evenly along the contact surface inside the outer tube.
Next, address the gearbox. Many ARK jockey wheels have a sealed or semi-sealed gearbox at the top; if yours has a grease point or an accessible cap, add fresh grease there to keep the internal gears and the thrust mechanism lubricated. Finally, lubricate the wheel bearing or axle and the swivel pivot if your model swings up. A few drops of grease or a smear on the axle keeps the wheel rolling freely and stops the swivel from seizing in the stowed position. Wipe away any excess so it does not collect new grit.
Step 4: Check the Clamp, Bracket, and Wheel
A perfectly serviced jockey wheel is still dangerous if the bracket that holds it to the drawbar fails. Inspect the clamp bracket and its bolts for cracks, elongated holes, and corrosion. Tighten the clamp bolts to spec and make sure the quick-release clamp, if fitted, locks firmly without slipping under load. A jockey wheel that creeps down the drawbar while you tow is a sign of a worn or under-tightened clamp.
Examine the wheel itself one more time. A pneumatic tyre should hold pressure and show even wear; a solid or foam-filled wheel should be free of chunks and cracks. If the wheel is worn flat on one side or the bearing is notchy after greasing, replace it now rather than mid-trip. Confirm the locating pin or bracket pin that stops the unit rotating is straight and engages cleanly.
Step 5: Test Under Load and Store Correctly
Reinstall the jockey wheel and test it under real load by lifting the trailer nose. The handle should turn with reasonable, consistent effort through the full range with no grinding or sudden hard spots. The wheel should roll and swivel freely when you maneuver the trailer by hand. If anything still feels rough, revisit the inspection step, as you may have missed a bent shaft or a failing bearing.
Between trips, store the trailer with the jockey wheel wound up and the inner shaft retracted into the outer tube, which keeps the greased shaft protected from UV and weather. If your trailer sits for long periods, wind the shaft in and out every couple of months to redistribute grease and stop it from setting.
The Practical Takeaway
An annual service of inspect, clean, grease, check the hardware, and test under load takes about an hour and dramatically extends the life of your jockey wheel. The two most important habits are keeping the inner shaft clean and greased, and storing the wheel retracted so it stays protected. Do this once a year, plus a quick wipe and re-grease after any muddy or salty trip, and your jockey wheel will outlast the trailer.
