17.When installing new differential bearings, reuse the
original shims or use new shims of the same thickness.
Press the bearing onto the differential case. If a new dif-
ferential case is being installed, start with a .020 inch
pack of shims under each differential bearing (Fig. 38).
Note: Shims are available in 0.003 in. (0.08 mm),
0.005 in. (0.13 mm), 0.010 in. (0.25 mm), and 0.030 in.
(0.76 mm) thickness.
18.Assemble new differential bearing cups onto differ-
ential bearing cones. Seat differential assembly with
drive gear on proper side of carrier into carrier bearing
cradles.
NOTE: This application requires that the ring gear teeth
face toward the spur gear cover.
19.The bearing cradles are designed to apply a slight
preload to the bearings. It is important to push both of the
bearing assemblies simultaneously into their saddles.
Install the bearing caps into their original position as pre-
viously marked. Tighten the cap screws to a torque of
30-45 ft-lbs. (41-61 Nm) (Fig. 39).
20.Using a dial indicator, check the ring gear backlash
in three equally spaced points. Ring gear backlash
should be .003-.007 inch (.076-.178 mm) and must not
vary more than .002 in. between points checked
(Fig. 40).
If the backlash is not in this range, move the shims which
are located beneath the differential bearings, from one
side to the other until the correct backlash is attained.
21.Check ring to pinion gear engagement (see Ring and
Pinion Gear Engagement in this chapter of the manual).
