2. Install the ring gear with shim in the gear case; then
while holding the pinion stationary, rock the ring gear
forward and back to determine if any backlash exists.
If no backlash exists, install a thicker shim and
recheck.
3. Install the bearing flange onto the gear case cover
making sure the alignment/locating pin engages the
locating hole in the cover; then make sure the bearing
flange is completely seated in the cover.

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
