Wheel Bearing Adjustment Disc Brakes

1. Make sure the brakes are fully released and do not drag.
2. Pull or push the tire at the top back and forth in order to check 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

1. Raise the vehicle until the wheel is free to spin.
2. Remove the axle shaft. Refer to Axle Shaft Replacement .
3. Remove the outer locknut.
4. Disengage the lock washer from the adjusting nut.
5. Remove the lock washer.
6. Adjust the adjusting nut.

6.1.	Make sure the bearing cones 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.

6.2.	Tighten the adjusting nut (using J 2222-C for American Axle equipped vehicles, or J 42855 for Dana Axle equipped vehicles) while rotating the hub assembly.

Tighten
Tighten the adjusting nut to 68 N·m (50 lb ft).

6.3.	Back off the adjusting nut. Retighten the adjusting nut while rotating the hub.

Tighten
Tighten the adjusting nut to 47 N·m (35 lb ft).

6.4.	Back off the adjusting nut 135-150 degrees.

1. Install the lock washer.
2. Bend one tang of the lock washer a minimum of 30 degrees over a flat of the adjusting nut.

3. Install the outer locknut

Tighten
Tighten the outer locknut to 88 N·m (65 lb ft).

4. Set the bearing adjustment to 0.025-0.25 mm (0.001-0.01 in).
5. Bend one tang of the lock washer a minimum of 60 degrees over a flat of the outer locknut.
6. Apply the wheel bearing grease into the bearings.
7. Install the axle shaft. Refer to Axle Shaft Replacement .
8. Lower the vehicle.
