Dirt is your trailer's biggest enemy. Once particles of dirt and dust get into your trailer's moving parts, it can cause friction and break down. Keeping your trailer's parts greased can help keep joints and axels moving smoothly. Before you take it back onto the road, do a little greasing first.
Pretty much any part of your trailer that's designed to move in some form or fashion or comes in contact with other parts should be kept lubricated to prevent corrosion and friction. Features like a winch, ball hitch, springs and tongue jack all require lubrication and you should keep them greased throughout the year. It's a good idea to make lubricating your trailer's moving parts an important part of your routine before each long trip.
It's important to keep all moving parts lubricated. One of the most important parts are the wheel bearings, the cylindrical rings that connect the wheel to the axle and allow for the wheel's free rotation. Since the wheels are extremely important to your trailer's ability to function well, it's important to maintain your wheel bearings. And since the wheel bearings and axles are a metal-on-metal combination, it's important to keep them well greased to prevent friction and potential wheel damage.
The wheel bearings are packed with inner bearings that allow the wheel bearings to move as a whole. Part of any trailer maintenance should include cleaning and greasing the wheel bearings for each wheel. We've included an in-depth guide to properly cleaning your wheel bearings on the Lots More Information page, but here's a quick run down of what you can expect. It may sound like a pain, but, again, it's extremely important to maintain your wheel bearings.
You'll first have to remove your tire and any hardware holding your wheel in place on your axle. You'll find your wheel bearing on the wheel hub, and it should be easily removed after removing the hardware holding it in place. You'll want to soak the wheel bearing in gasoline to loosen grime and old grease. Remove the old seal, then the inner bearing. Thoroughly clean the inner bearing and the wheel bearing as a whole.
After the parts are completely dry, replace the inner bearing and seal the wheel bearing. Gently add grease to prevent breaking the seal, and wipe off any excess grease. Now's also a good time to grease the axle. After you reinstall the wheel bearings and the wheel, move on to the next one.
