If an abnormal noise is heard from the propeller shaft
while driving, some parts of the propeller shaft may
be worn or damaged, or some mounting bolts may
be loose.

SYMPTOM PROCEDURES

INSPECTION PROCEDURE 1: Noise at Start

DIAGNOSIS

STEP 1. Check if the propeller shaft flange yoke
and rear differential connecting nuts and the
center bearing mounting nuts are loose.
Propeller shaft flange yoke and rear differential con-
necting nuts tightening torque: 54

± 5 N⋅ m (40 ± 4

ft-lb)
Center bearing mounting nuts tightening torque: 41

±

5 N

⋅ m (30 ± 3 ft-lb)

Q: Are the connecting nuts and mounting nuts

tightened to the specified torque?
YES :

Go to Step 2.

NO :

Tighten the connecting nuts and mounting
nuts to the specified torque. Then go to Step
3.

STEP 2. Check the sleeve yoke's spline of front
propeller shaft for wear.

Q: Is wear apparent?

YES :

Replace the propeller shaft. Then go to Step

3.

NO :

Go to Step 3.

STEP 3. Retest the system.

Q: Is the abnormal noise eliminated?

YES :

The procedure is complete.

NO :

Recheck from Step 1.

INSPECTION PROCEDURE 2: Noise and Vibration at High Speed

DIAGNOSIS

STEP 1. Check the propeller shaft run-out.
(1) Remove the propeller shaft. (Refer to

P.25-6

.)

ACX00643

(2) Measure the propeller shaft runout.

Limit: 0.5 mm (0.02 inch)

Q: Is the measured value within the limit?

YES : Go to Step 2.
NO : Replace the propeller shaft. Then go to Step 2.
