NOTE:

If reusing locking differential side gear thrust sleeve, proceed to step 5. If replacing the locking differential side gear thrust sleeve, proceed to step 6.

Using the J 29710 installer and a hydraulic press, install the locking differential side gear thrust sleeve until it is fully seated on the locking differential side gear.
If the cam side gear or the thrust sleeve has been replaced, measure the overall length of the gear assembly by doing the following:
1. Place the locking differential clutch disc thrust washer on top of the thrust sleeve.
2. Measure the overall length of the gear assembly from the front of the cam side gear to the back of the locking differential clutch disc thrust washer.
3. Compare this measurement to the measurement obtained during disassembly.
4. If the new reading is more than 0.762 mm (0.003 in) greater than or less than the original, select a locking differential clutch disc thrust washer that will return the reading closest to the original reading.
Align the locking differential clutch disc set.

NOTE:

Applying a small amount of chassis grease to the locking differential guides will hold them in place during the installation procedure.

Install the and apply a small amount of chassis grease to the locking differential guides. Refer to Adhesives, Fluids, Lubricants, and Sealers .
