GENERAL INFORMATION

M1251000100421

The 2-piece, 3-joint type propeller shaft with a center 
bearing is adopted.
It has the following features:

• The DOJ, which is of less sliding resistance, is 

used for the No.2 joint to reduce idling vibration.

• An insulator is installed to the vehicle body joint of 

the center bearing to reduce vibration.

• The heat protector is adopted to the center bear-

ing bracket.

• Inside the rear propeller shaft, the dynamic 

damper is integrated to reduce a booming noise 
caused by the resonance at the high engine 
speed.

• Adopting the friction welding method, the installa-

tion structure is streamlined to reduce weight.

• Lead-free grease is used for the universal joint.

PROPELLER SHAFT DIAGNOSIS

INTRODUCTION TO PROPELLER SHAFT DIAGNOSIS

M1251001800122

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.

PROPELLER SHAFT DIAGNOSTIC TROUBLESHOOTING STRATEGY

M1251001900130

Use these steps to plan your diagnostic strategy. If 
you follow them carefully, you will be sure that you 
have exhausted all of the possible ways to find a pro-
peller shaft 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 CHART

M1251002000129

SYMPTOM PROCEDURES

INSPECTION PROCEDURE 1: Noise at Start

DIAGNOSIS

STEP 1. Check if the propeller shaft mounting 
nuts and the center bearing mounting nuts are 
loose (Refer to 

P.25-7

).

Q: Are the mounting nuts tightened to the specified 

torque?
YES : 

Go to Step 2.

NO : 

Tighten the propeller shaft mounting nuts to 
54 

± 5 N⋅m (40 ± 3 ft-lb). Tighten the center 

bearing mounting nuts to 41 

± 5 N⋅m (30 ± 3 

ft-lb). Then go to Step 4.

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

Q: Is wear apparent?

YES : 

Replace the propeller shaft. Then go to Step 

4.

NO : 

Go to Step 3.

STEP 3. Check the propeller shaft for looseness.

Q: Is looseness recognized?

YES : 

Replace the propeller shaft. Then go to Step 

4.

NO : 

Go to Step 4.

STEP 4. 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 runout.
Q: Is the measured value within the limit; Front :0.5 mm 

(0.02 inch) or Rear: 0.8 mm (0.03 inch) ?
YES : Go to Step 2. 
NO :  Replace the propeller shaft. Then go to Step 3.
