Regular maintenance of repacking trailer wheel bearings is highly recommended by many trailer manufacturers, either every year for trailers that get normal use or at least every 20,000 miles. To complete this task, the following tools are needed: a jack, a pair of jack stands, a large flat-head screwdriver, a hammer, and a needle-nose pliers. In addition, clean rags, a small pan, about a quart of kerosene, and a spray can of brake cleaner are also required.To start, loosen the lug nuts on one wheel and use the jack to raise that side of the trailer. Then, use jack stands to support the trailer and spin the wheel while listening for trailer bearing sounds. If the wheel spins freely and quietly, proceed with repacking the bearings. However, if there is friction or a growling sound, it is likely due to a bad bearing or spindle and the trailer should be taken to a service center for bearing replacement.Figure A can be downloaded and printed from the Additional Information section below to assist with following the steps for repacking trailer bearings. To start, remove the wheel and lug nuts, making sure the trailer is supported by jack stands and the opposite wheel is blocked. Pry the dust cap loose with a large screwdriver, straighten the ends of the cotter pin, and pull it out with needle-nose pliers.Next, remove the hub by taking off the retaining nut and washer and pulling the hub off the spindle, being careful since the trailer bearings will come out with the hub. Set the bearings on clean newspaper and remove the rear bearing and seal by tapping along the rim of the bearing with a block of wood and a hammer. If the seal is rusted to the back of the hub, spray a little WD-40 on the back to help loosen it. If the seal is damaged, replace it.Clean all the grease from the bearings, races, and seal with a brush in a small pan of kerosene. Inspect them for signs of wear and replace them if they look suspect. Once the bearings and parts are clean, spray them with brake cleaner and set them aside to dry. Wipe the spindle and the inside of the hub with a clean rag to remove all the grease, and clean them with brake cleaner as well.Push the grease into the bearings from the wide side of the bearing, working until the cage and rollers are filled. Then coat the inside of the hub with grease, tap the seal back onto the rear of the hub with a block of wood and hammer, and install the hub and bearings back on the spindle. Thread the nut back onto the spindle and turn it clockwise, spinning the hub a few times as you tighten to ensure proper seating of the bearings. Tighten the nut firmly and then back it off about an eighth of a turn until the hole in the spindle aligns with a space in the nut. Push in a new cotter pin, available at hardware and auto parts stores, and bend the ends of the pin to keep it from working its way out. Tap the dust cap back into place, coat the lug threads with anti-seize compound, reinstall the wheel, and tighten the lug nuts. Repeat this process for each wheel.
