Tips and Tricks

Use a chisel and hammer to carefully tap the old bearing off the hub. Do not use a hammer alone, as this can damage the hub.

Apply a small amount of anti-seize compound to the hub before installing the new bearing. This will help prevent future corrosion and seizing.

Torque the bearing nut to the specified torque using a torque wrench. Overtightening can damage the bearing, while undertightening can cause it to fail prematurely.
