NOTE: To determine the appropriate shim, proceed

to step 3.
3. Using an appropriate tool, lock the pinion gear in
place.
XX320
4. Mount a dial indicator so the tip is contacting a tooth
on the pinion shaft.
TA095
5. While pushing in on the front output shaft, and while
rocking the shaft back and forth, note the maximum
backlash reading on the gauge.
XX321
6. Acceptable backlash range is 0.076-0.241 mm
(0.003-0.0095 in.).
NOTE: If backlash measurement is within the

acceptable range, no correction is necessary.
7. If backlash measurement is less than specified,
remove the existing shim and install a new thicker
shim (from shim kit).
TA102
8. If backlash measurement is more than specified,
remove the existing shim and install a thinner shim.
NOTE: Continue to remove, measure, and install

until backlash measurement is within tolerance. Note
the following chart.
Backlash Measurement
Under 0.076 mm (0.003 in.)
At 0.076-0.241 mm (0.003-0.0095 in.)
Over 0.241 mm (0.0095 in.)
9. Tape the splined portion of the pinion shaft to protect
the seal; then using an appropriate seal installer,
install the front output seal so it seats fully past the
chamfer of the case.
TA129
TA130
ASSEMBLING HALVES
1. Install the input shaft assembly. Take care not to
damage the seal.
