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 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
).
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.
