Wheel Bearing Adjustment

Preliminary Inspection

Important: Ensure the brakes are fully released and do not drag.

Pull or push the tire at the top back and forth in order to test the wheel bearing play.

* Use a pry bar under the tire as an alternative.
* If the wheel bearing adjustment is correct, the movement will be barely noticeable.
* If the movement is excessive, adjust the bearings.
