Wheel Bearing Adjustment Drum Brakes

1. Ensure that the brakes are fully released and do not drag.
2. Pull or push the tire at the top back and forth in order to inspect the wheel bearing play.

•	Use a pry bar under the tire as an alternative.

•	If the wheel bearing adjustment is correct, movement of the brake drum in relation to the brake backing plate will be barely noticeable.

•	If the movement of the brake drum in relation to the brake backing plate is excessive, adjust the bearings.

Tools Required

J 2222-C Wheel Bearing Nut Wrench

1. Raise the vehicle until the wheel is free to spin.



2. Remove the axle shaft (5). Refer to Axle Shaft Replacement .
3. Ensure that the following components are free of chips, burrs and shavings:

•	The keyway

•	The threads

•	The adjusting nut (8)

4. Remove the retaining ring (10).
5. Remove the wheel bearing adjusting key (9).
6. Ensure the bearings are seated and in contact with the spindle shoulder.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
