Important Operations

Before disassembling, make a pattern check using the method
described later in this section under "Gear Tooth Contact
Pattern Check and Adjustments".  This check will help
determine what service should be performaed on the
differential components.
On some bench operations, it may be advantageous to use a
holding fixture and a holding fixture base.
Tool 5-8840-0275-0 (J-37264) and 5-8840-0003-0 (J-3289-20)
are available tools that work well for this purpose.

1. Bearing Cap
Apply an alignment mark to the side bearing cap and
differential carrier.

2. Side Bearing Outer Race
After removal, keep the right and left side bearing assemblies
separate to maintain inner and outer race combinations.

4. Side Bearing

5. Backlash and Side Bearing Preload Adjusting Shim
Remover : 5-8840-0013-0 (J-22888)
Adapter : 9-8521-1743-0 (J-8107-2) (194 mm)

5-8840-2196-0 (J-8107-4) (220 mm)

Carefully record the thickness of each side bearing and each
shim pack.  Keep them separated and in order for later
reassembly.

6. Flange nut and washer (194 mm)
Holder : 5-8840-0133-0

(J-8614-01)

Flange Nut and Washer (220 mm)

Holder : 5-8840-2157-0

(J-37221)

8. Drive Pinion Shaft Assembly
Hold a soft metal rod against the end of the drive pinion.  Drive
out the pinion from the carrier by tapping the hammer against
the metal rod.
Installer : 9-8521-5032-0

9. Inner Bearing
Remove the pinion bearing using a separator and a press.
Separator : 5-8840-0015-0 (194 mm)

(J-22912-01)

: 5-8840-2197-0 (220 mm)
