Inspection Procedure 1: Abnormal Noise
INSPECTION PROCEDURE 1: Abnormal NoiseDIAGNOSIS
STEP 1. Check the wheel nuts for looseness.
Q: Are the wheel nuts loosened?
YES: Tighten the wheel nuts to the specified torque 98 ± 10 Nm (73 ± 7 ft. lbs.). Then go to Step 3.
NO: Go to Step 2.
STEP 2. Check the wheel bearing end play.
1. Remove the caliper assembly, and suspend the caliper assembly with a wire and remove the brake disc.
2. 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: Tighten the self-locking nut to the specified torque 175 ± 25 Nm (130 ± 18 ft. lbs.) and check the end play again. Replace the rear hub assembly if an adjustment cannot be made to within the limit. Then go to Step 4.
STEP 3. Check the rear hub rotary-sliding resistance.
1. Remove the caliper assembly, and suspend the caliper assembly with a wire and remove the brake disc.
2. Turn the hub a few times to seat the bearing.
3. 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 N (4.3 lb.)
Q: Is the rear hub rotary-sliding resistance within the limit?
YES: Go to Step 4.
NO: Loosen the self-locking nut and then tighten it to the specified torque 175 ± 25 Nm (130 ± 18 ft. lbs.) and check the rear hub rotary sliding resistance again. Replace the rear hub assembly if an adjustment cannot be made to within the limit. Then go to Step 4
STEP 4. Retest the systems.
Q: Are abnormal noises generated?
YES: Return to Step 1.
NO: The procedure is complete.
