ADJUSTMENT

The wheel hub bearing assembly is not repairable; it must be replaced when defective.

  1. Verify that the wheel bearings operate smoothly.
  2. Install a dial indicator to the wheel hub bearing assembly and check the axial end-play; it should be less than 0.0020 in. (0.05 mm).
  3. If the axial end-play exceeds specifications, the wheel bearing must be replaced.
