REAR AXLE DIAGNOSIS

INTRODUCTION

M12701000041USA0000010000

Noise from the driveshaft or differential may be
caused by defects in the components.

TROUBLESHOOTING STRATEGY

M12701000042USA0000010000

Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure that you
have exhausted most of the possible ways to find a
rear axle fault.

1.

Gather information from the customer.

2.

Verify that the condition described by the customer
exists.

3.

Find the malfunction by following the Symptom
Chart.

4.

Verify malfunction is eliminated.

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.
