DIAGNOSIS
1. Check the treadwear on the rear tires.

Yes - Go to step 2.
No - Go to REPAIR PROCEDURE.
2. Swap the rear tires with known-good tires, then test-drive the vehicle.
Do you hear a howl or growl from either of the rear wheel(s)?
Yes - Go to REPAIR PROCEDURE.
No - This service bulletin does not apply. Replace the rear tires (if authorized by the customer), then troubleshoot the tire wear problem.
REPAIR PROCEDURE
1. Release the parking brake, and raise the vehicle on a lift.
2. Remove the wheel nuts and the rear wheel on the affected side.
3. Remove the brake hose mounting bracket bolt, the brake caliper bracket mounting bolts, and the brake caliper.
NOTE:
To avoid brake hose and brake caliper damage, use a short piece of wire to hang the caliper from the undercarriage.
4. Remove the brake disc flat screws, then remove the brake disc from the hub.
NOTE:
If the brake disc is stuck to the hub, thread two 8 x 1.25 mm bolts into the brake disc to push it away from the hub. Turn each bolt 90 degrees at a time to prevent the brake disc from binding.
5. Remove the hub bearing unit and its 0-ring from the wheel (four bolts).
6. Check for rust on the noisy hub bearing unit.

8. Install a new hub bearing unit with a new 0-ring on the affected side. Torque the hub bearing unit bolts to 98 N.m (72 lb-ft).
9. Reinstall the brake disc. Torque the brake disc flat screws to 9.8 N.m (7.2 lb-ft).
10. Reinstall the brake caliper. Torque the caliper bracket mounting bolts to 108 N.m (80 lb-ft).
