Torque is transmitted from the transmission to the
axle through propeller shaft and universal joint
assembles. All propeller shafts are the balanced
tubular type. A splined slip joint is provided in some
drivelines.

Since the propeller shaft is total balanced carefully,
welding or any other modification are not permitted. 
Alignment marks should be applied to each
propeller shaft before removal.

Be sure vehicle is stopped, engine is not running,
brake is secured and vehicle is secured to prevent
injury.

Be careful not to grip the propeller shaft tube too
tightly in the bise as this will be cause deformation.

TROUBLESHOOTING
Refer to this Section to quickly diagnose and repair
rear axle problems.
Each troubleshooting chart has three headings
arranged from left to right.
(1) Checkpoint
(2) Trouble Cause
(3) Countermeasure
This Section is divided into five sub-sections:
1. Abnormal Rear Axle Noise
1) Noise when the engine is driving the vehicle
2) Noise when the vehicle is coasting
3) Intermittent noise
4) Noise when the vehicle is turning
5) Constant noise
2. Vibration
3. Oil Leakage
1) Differential carrier leakage
2) Axle case leakage
3) Axle case to inside hub leakage
4) Axle case to inside brake drum leakage
4. Power Not Being Transmitted to the Wheels
(Propeller Shaft Operation is Normal)
