Install the axle shaft assembly on the opposite side and push it
in until it fits against the differential thrust block. Then,
measure the clearance (t) between the bearing holder and the
axle case flange and determine the thickness of the shim to be
installed by the following formula :
Measured clearance (t) + 0.3 mm (0.012 in) = thickness of
shim to be installed.

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)
