Gear Tooth Contact Pattern Check and

Adjustment

Apply a thin coat of prussian blue or equivalent to the faces of
7 - 8 teeth of the ring gear.  Check the impression of contact
obtained on the ring gear teeth and make necessary
adjustment as described below if the contact is abnormal.

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)
