Trailer wheel bearings support the wheel hubs on the axles. Bearings require a certain amount of pressure, otherwise referred to as preload. The specific amount of preload determines the number of bearings that support the wheel hubs at any given time. Cone flats thread onto the axles and press bearing cones against the bearings. Adjusting bearing cone preload prolongs the life of the bearings. With proper preload, light drag should be noticed when spinning the wheels.
Wheels with quick-release levers present a challenge. Closing the lever alters the preload. Adjusting bearings on wheels that have quick-release levers may take several attempts.


If you ever have to open up a wheel hub on a trailer, chances are you're going in to either grease the ina bearings or replace them because you didn't. The key is to make sure the Trailer wheel  bearings stay greased on your own terms, so you don't find yourself replacing them on the side of the road at an inopportune time.


When installing Trailer wheel  bearings or replacing them, you need a pair of pliers, a lug wrench, a hammer, a flathead screwdriver and the necessary means to jack the wheel up safely. Be sure to loosen the lug nuts with the lug wrench first. Once the wheel is in the air, all you have to do is follow a few simple steps.

The Trailer  wheel bearings sit between a cone screwed to the wheel axle and the cup in the wheel hub. They must be properly adjusted and greased. To find out if they need greasing without taking everything apart, simply remove the wheel from the bike, support the axle horizontally with your fingers, and turn the wheel slowly--try not to tilt the axle as it rotates. If the wheel does not turn smoothly or you can feel tiny bumps in your fingers, then you must dismantle the bearing assembly and service the bearings.
