CAUTION<br />
A THRUST WASHER, DIFFERENTIAL SIDE<br />
GEAR AND PINION GEAR ARE MACHINED<br />
AS A MATCHED SET. WHEN YOU REPLACE<br />
ANY OF THESE PARTS, YOU MUST IN-<br />
STALL A NEW MATCHED SET. DO NOT MIX<br />
OLD AND NEW PARTS. DAMAGE TO COM-<br />
PONENTS CAN RESULT.<br />
3. Inspect the following main differential assembly<br />
parts for wear or stress. Replace<br />
parts that are damaged. Figure 4.7.<br />
• Inside surfaces of both case halves<br />
• Both surfaces of all thrust washers<br />
• The four trunnion ends of the u-joint of differential<br />
• Teeth and splines of both differential side<br />
gears<br />
• Teeth and bore of all differential pinions<br />

4. Inspect the axle shafts for wear and cracks at<br />
the flange, shaft and splines. Replace the axle<br />
shafts, if necessary.<br />
5. Inspect the breather plug.<br />
Prepare Parts for Reassembly<br />
A. Remove the breather plug from the axle<br />
housing.<br />
B. Clean the breather plug.<br />
• If the breather plug remains dirty after<br />
cleaning:Replace the breathe plugr.<br />
C. Apply compressed air to the breather.<br />
• If compressed air does not pass through the<br />
breather plug: Replace the breather plug.<br />
D. Install the breather plug in the axle housing.<br />
Repair or Replace Parts<br />
NOTE:<br />
Threads must be without damage and clean<br />
so that accurate adjustments and correct<br />
torque values can be applied to fasteners<br />
and parts.<br />
1. Replace any fastener if the corners of the<br />
head are worn.<br />
2. Replace the washers if damaged.<br />
3. Replace the gaskets, oil seals or grease seals<br />
at the time of axle or differential repair.<br />
4. Clean the parts and apply new silicone gasket<br />
material where required when the axle or<br />
differential is assembled. Figure 4.8.<br />
Remove silicone<br />
gasket from parts.<br />
Figure 4.8<br />
5. Remove nicks, mars and burrs from parts<br />
with machined or ground surfaces. Use a fine<br />
file, india stone, emery cloth or crocus cloth.<br />
6. Clean and repair the threads of fasteners and<br />
holes.<br />
