The wheel bearing does not usually require maintenance. If the bearing growls during operation, drags or turns roughly when the hub is turned by hand, replace the bearing.

The use of a hydraulic press and appropriate adapters is necessary to perform this procedure.

  1. Raise and support the vehicle safely.
  2.  
  3. Remove the rear wheel.
  4.  
  5. Remove the hub cap.
  6.  
  7. Remove the cotter pin, followed by the serrated nut cover. Unfasten and remove the wheel bearing locknut and washer.
  8.  

When removing the axle shaft, cover the CV-boots with shop rags to prevent damaging them.

  1. Separate the axle shaft from the knuckle by lightly tapping it using a plastic hammer. If the shaft is hard to remove, a jaw type puller may be used to force the shaft through the hub.
  2.  
  3. Remove the brake rotor or brake drum.
  4.  
  5. Remove the knuckle.
  6.
