1. Secure the gear case in a holding fixture with the
cover side up; then install a dial indicator contacting
the ring gear axle flange.
2. Zero the dial indicator; then push the ring gear
toward the dial indicator and release. End-play
should be 0.004-0.008 in.
3. To increase end-play, decrease the shim thickness. To
decrease end-play, increase the shim thickness.
 NOTE: Once proper backlash and end play are
established, the gear case can be assembled (see
Assembling Differential Assembly in this sub-sec-
tion).
RING GEAR/THRUST BUTTON
Removing
Remove the thrust button from the gear case cover
(left-hand threads). Account for a shim.
Inspecting
1. Inspect the ring gear for excessive wear or discolor-
ation.
2. Inspect the thrust button for excessive wear or dis-
coloration.
3. Inspect the bearings for discoloration, roughness, or
excessive wear.
Installing/Shimming
 NOTE: Ring gear end-play must be adjusted prior to
selecting shim for the thrust button.
1. Install the thrust button with shim into the gear case
cover and tighten securely (left-hand threads).

2. Place the ring gear with selected shim into the cover
and measure the ring gear to thrust button clearance
with a thickness gauge. Clearance should be
GC065
0.002-0.004 in.
3. If clearance is as specified, remove the ring gear and
thrust button; then place a drop of red Loctite #271
on the threads and tighten to 8 ft-lb (left-hand
threads).
4. If clearance is not as specified, repeat steps 1 and 2
using thicker (clearance too great) or thinner (clear-
ance too small) until correct specification is reached.
Assembling Differential Assembly
CC888
1. With the pinion gear and new bearings installed,
place the selected (backlash) shim on the gear case
side of the ring gear with the chamfered side toward
the ring gear; then install into gear case/differential
housing.
