INSPECTION PROCEDURE 1: Abnormal Noise: Diagnosis

Q: Are the rear hub assembly installation bolts loosened? 

• YES:  Tighten the rear hub assembly installation bolts to the specified torque 95 ± 14 N.m (70 ± 10 ft-lb). Then go to  Step 3.
• NO:  Go to Step 2.

1. Remove the brake drum. < Vehicles with drum brake >
2. Remove the brake caliper assembly, and suspend the brake caliper assembly with a wire and remove the brake disk. < Vehicles with disk brake >
3. Check the bearing's end play. Place a dial gauge against the hub surface, then move the hub in the axial direction and check whether or not there is end play.

   Limit: 0.05 mm (0.002 inch) 

Q: Is the wheel bearing end play within the limit? 

• YES:  Go to Step 3.
• NO:  Replace the rear hub assembly, then go to  Step 4.

1. Remove the brake drum. < Vehicles with drum brake >
2. Remove the brake caliper assembly, and suspend the brake caliper assembly with a wire and remove the brake disk. < Vehicles with disk brake >
3. Turn the hub a few times to seat the bearing.
4. Wind a rope around the hub bolt and turn the hub by pulling at a 90 degree angle with a spring balance. Measure to determine whether or not the rotary-sliding resistance of the rear hub is at the limit value.

   Limit: 19.2 N (4.32 lb) 

Q: Is the rear hub rotary-sliding resistance within the limit? 

• YES:  Go to Step 4.
• NO:  Replace the rear hub assembly if an adjustment cannot be made to within the limit. Then go to Step 4.
