Trailer Hub and Drum 
1. Remove the wheel
Remove the lug nut and wheel. Ensure that the trailer is supported by a jack bracket and the other wheel is blocked.
2. Remove the dust cover
Use a large screwdriver to pry open the dust cover.
3. Remove the split pin
Straighten both ends of the cotter pin and pull it out with Needle-nose pliers.
4. Remove the wheel hub
Remove the fixing nut and washer, and then pull the hub off the spindle. Be careful that the trailer bearings may come off the wheel hub. Place the bearing on a clean newspaper.
5. Remove the rear bearing and seal
Remove the rear bearing and seal, and use a wooden block and hammer to strike along the edge of the bearing. If the seal on the back of the wheel hub rusts, spray a little WD-40 on the back to help loosen it. If the seal is damaged, replace it. Use a brush to clean all grease on the bearings, races, and seals in a small can of kerosene. Check them for signs of wear, and if any signs of wear are suspected, replace them. After cleaning the bearings and parts, spray brake cleaner and let it dry on one side. Wipe the inside of the spindle and hub with a clean cloth, remove all grease, and clean with brake cleaner.
6. Install lubricating grease into the bearing
Push the grease into the bearing from the wide side. Continue to push the grease into the drum until the holder and drum are full. Next, apply lubricating grease on the inside of the wheel hub. Use a wooden block and hammer to knock the seal back onto the rear of the hub, and then install the hub and bearing back onto the spindle.
7. Reassembly of the wheel hub
Screw the nut back onto the spindle and turn it clockwise. Rotate the hub several times when tightening to ensure the bearings are correctly seated. Tighten the nut. Now back off the nut by approximately one eighth of a turn until the hole on the spindle aligns with the space in the nut. Push in a new cotter pin (available at Hardware stores and auto parts stores) and bend the end of the cotter pin to prevent it from falling off. Gently knock the dust cover back into place. Apply anti-seize compound to the lug threads, reinstall the wheel, and tighten the nuts. Perform the same operation on each wheel.
