Replacing rear wheel bearings on a live-axle rear suspension requires a few extra steps when compared to a unitized bearing. To remove the axle shaft, the differential must be accessed and the clips that hold the axle in the differential must be removed.
A seal must always be installed so that the sealing lip is facing the fluid to be sealed. This is because the lip is made so that pressure applied to it from the “wet” side of the seal will tend to increase the pressure the lip applies to the shaft. If the seal is installed backwards, pressure acting on the “wrong” side of the lip will cause it to lift from the shaft, resulting in leakage. On most seals, the correct side is obvious; however, on others it is not.
Wheel bearings are either of the ball or tapered roller variety. Front wheel bearing applications are an angular-type ball bearing, which will accept greater thrust loads than a Conrad-type bearing, and will accept a 100 percent load in the radial or thrust position and any combination of a 100 percent load. A tapered roller bearing
