2. Assemble the J 29763 (5) to the J 36601-3 (4) and J 36601-7 (1). See Special Tools and Equipment .  

3. Assemble the J 21777-8 (3) onto the J 36601-7 (1).  

4. Install the pinion bearings and hold them in place.  

5. Insert the J 36601-7 (1) with the J 21777-8 (3) through the pinion bearings.  

6. Install the J 36601-5 (2), the washer, and the nut to the J 36601-7 (1).  

7. While holding the J 36601-3 (4) stationary, install an inch-pound torque wrench on the nut and tighten the 

nut until a rotating torque of 1.1-2.3 N.m (10-20 lb in) is obtained. 

Rotate the assembly several times in both directions in order to seat the pinion bearings. 

8. Check the rotating torque of the assembly. If the torque is less than 1.0 N.m (10 lb in), tighten the nut on 

the J 36601-7 until a rotating torque of 1.1-2.3 N.m (10-20 lb in) is obtained.

9. Adjust the J 29763 (2) to the differential bearing bore by doing the following: 

1. Loosen the lock nut on the J 29763 . See Special Tools and Equipment .  

2. Place the contact pad of the J 36601 on the differential side bearing bore. See Special Tools and 

Equipment .  

3. With the contact pad of the J 36601 touching the differential side bearing bore, push down on the J 

29763 until the needle of the J 29763 has turned 3/4 of a turn clockwise. See Special Tools and 
Equipment .  

4. Tighten the lock nut of the J 29763 . See Special Tools and Equipment .  

IMPORTANT: The left side differential bearing adjuster assembly must be removed prior 

to placing the J 36601-3 in the differential side bearing bore.

10. Rotate the J 36601 (1) back and forth until the needle of the J 29763 (2) indicates the lowest point in the 

differential side bearing bore. See Special Tools and Equipment .  

11. At the lowest point of deflection, move the housing of the J 29763 until the needle indicates ZERO. See 

Special Tools and Equipment .  

12. Move the J 36601 back and forth again to verify the zero setting. See Special Tools and Equipment . 

Adjust the housing of the J 29763 as necessary to set the needle to ZERO. See Special Tools and 
Equipment .

13. After the ZERO setting is obtained and verified, grasp the J 36601 (1) by the flats and move the J 36601 

out of the differential side bearing bore. See Special Tools and Equipment .  

14. The value indicated on the J 29763 (2) is the thickness of the shim needed in order to set the depth of the 

pinion. See Special Tools and Equipment .  

15. Select the shim that indicates the proper thickness. Measure the shim with a micrometer in order to verify 

that the thickness is correct.
