6. Zero the dial indicator; then while holding the pinion
stationary, rock the ring gear assembly forward and
back and record the backlash. Backlash must be
0.011-0.015 in. If backlash is within specifications,
proceed to Ring Gear End-Play. If backlash is not
within specifications, increase shim thickness to
increase backlash or decrease shim thickness to
decrease backlash.
 NOTE: Higher backlash settings usually result in
quieter gear operation.
Ring Gear End-Play
After correcting backlash, ring gear end-play can be
adjusted. To adjust end-play, use the following proce-
dure.
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 estab-
lished, the gear case can be assembled (see Assem-
bling Differential Assembly in this sub-section).
Assembling Differential Assembly
1. With the pinion gear and new bearings installed, place
the selected (backlash) shim on the gear case side of
GC039A
the ring gear with the chamfered side toward the ring
gear; then install into gear case/differential housing.
GC037A
2. Place the selected (end-play) shim, chamfered side
toward the gear, onto the cover side of the ring gear.
 NOTE: The spider and ring gear assembly must be
GC035
replaced as a complete unit.
