Determine Shim Thickness
There are two possible methods for determining the
thickness of shims needed for the right differential
housing. Review each procedure to determine which
method best fits your application.
Method “A”
See Figures 5-85 and 5-86.
Figure 5-85
1. Measure the distance (1) from the side of the
differential bearing (2) to the housing flange surface
(3).
Figure 5-86
2. Measure the distance (6) from the right differential
housing flange (4) to the bottom of the bearing bore
(5).
3. Subtract distance (1) from distance (6). From the
answer, add 0.004 in. (0.1 mm). This is the thickness
of the shim pack needed.
4. Continue assembly of the differential housings, step
11 of “Assembly” on page 5-74.
Method “B”
See Figure 5-87.
Figure 5-87
1. Build a temporary shim pack (2) equal to 0.030 in.
(0.76 mm), and place it on the bearing bore of the
right differential housing (1).
2. Place the right differential housing (1) on the left
differential housing (4).
NOTICE
3. Install the differential housing bolts evenly to hand
tight.
4. Using a feeler gauge, measure the gap (3) between
the housings.
5. Add 0.004 in. (0.1 mm) to the dimension obtained in
step 3, then subtract the total from 0.030 in.
(0.76 mm). This is the thickness of the shim pack
needed.
6. Separate the differential housings.
7. Remove the temporary shim pack (2).
8. Continue assembly of the differential housings, step
11 of “Assembly” on page 5-74.

Tightening the differential housing bolts at this
time could result in damage to the differential
housings or other components.
