INSPECTION PROCEDURE 1: Abnormal Noise: Diagnosis

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

STEP 1. Check the rear hub assembly installation bolts for looseness.
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.
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 disk.
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: Replace the rear hub assembly, 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 disk.
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: 24.5 N (5.51 pounds)
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.

Q: Are abnormal noises generated?
- YES: Return to Step 1.
- NO: The procedure is complete.
