How to repack trailer wheel bearings for your boat trailer, utility trailer, open trailer or other trailer. In this video I cover all of the steps for repacking the wheel bearing in a small trailer including checking the wheel for bearing issues, removing the trailer wheel hub, visually inspecting the hub axle, bearings, races, and axle seals as well as ordering the correct parts, repacking the wheel bearings and installing axle seals and putting the wheel assembly back on the trailer.

Boat trailer bearing replacement is not a hard job - but it is a messy job! It is important to inspect and maintain the wheel bearings on trailers and it can be especially important to properly maintain the wheel bearings on a boat trailer because those axles are often submerged in water on a regular basis. For this video I purchased the trailer wheel hub parts from eTrailer.com (who are not a sponsor of this video). An important component is the inner seal that keeps grease from leaking out and helps to keep water out of the bearings. This seal is often referred to as: trailer wheel seal, trailer axle seal, inner grease seal, wheel bearing seal, or any combination of those words!

I try to provide step-by-step instructions for repacking and replacing wheel bearings, axle seals, grease caps (or dust caps), castle nuts, and cotter pins. See the complete process from checking the bearings for wear, removal of the wheel (or tire and rim), measuring components, hand repacking of the wheel bearings, installing new bearing grease seals and reinstalling everything back onto the trailer axle.
