5. Place the Backlash Gauge Tool into the splines of
the ring gear and install a dial indicator making
sure it contacts the gauge at a 90° angle and on the
index mark.
6. Zero the dial indicator; then while holding the pin-
ion 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 specifica-
tions, proceed to Ring Gear End-Play. If backlash
is not within specifications, increase shim thick-
ness to increase backlash or decrease shim thick-
ness 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 contact-
ing 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 thick-
ness. 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).
