SYMPTOM PROCEDURES

INSPECTION PROCEDURE 1: Noise during Wheel Rotation <DRIVESHAFT>

M12701000045USA0000010000

DIAGNOSIS

STEP 1. Check the wheel bearing end play.

ZC5018670000

(1)

Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.

(2)

Fit the dial gauge as shown in the diagram and move the hub
in the axial direction to measure the play.

Limit: 0.05 mm (0.002 inch)

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

YES:

Go to step 2.

NO:

Replace the part, then go to Step 4.

STEP 2. Check if the driveshaft is bent.

Q:Is the driveshaft bent?

YES:

Replace the part. Then go to Step 3.

NO:

Go to Step 4.

STEP3. Check the driveshaft assembly for wear or damage.

Q:Is the driveshaft assembly worn or damaged?

YES:

Replace the driveshaft assembly. Then go to Step 4.

NO:

There is no action to be taken.

STEP 4. Retest the system.

Q:Is the abnormal noise eliminated?

YES:

The procedure is complete.

NO:

Start over at Step 1.
