Rear Knuckle: Testing and Inspection

SYMPTOM PROCEDURES

INSPECTION PROCEDURE 1: Abnormal Noise

DIAGNOSIS

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 73 ± 7 Nm (54 ± 5 ft-lb). Then go to Step 4.
NO Go to Step 2.
STEP 2. Check the wheel bearing end play.

(1)Remove the brake caliper assembly, and suspend the brake 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 Replace the rear hub assembly, then go to Step 4.

STEP 3. Check the rear hub rotary-sliding resistance.

(1)Remove the brake caliper assembly, and suspend the brake 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 within the limit value.
Limit: 24 N (5.4 pounds)

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

YES Go to Step 4.

NO Replace the rear hub assembly, 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.
