7. Remove differential assembly (items 20 to 29) from
the gear case.
8. Remove eight (8) cap screws that secure spiral gear
(item 21) to the differential housing. Remove gear from
housing.
9. Remove dowel pin (item 25) that retains differential
gear pin in the differential housing. Discard the removed
pin.
10.Remove differential gear pin (item 26), pinion gears
(item 27) and output gear (item 23) from the differential
housing. Also, remove output gear (item 22) from spiral
gear.
11. Remove oil seals from output cover and gear case
taking care to not damage bores in cases during seal re-
moval. Discard removed seals.
12.If necessary, remove shift fork from cover (Fig. 50):
A. Remove Torx screws and fork retainers that se-
cure shift fork to output cover.
B. Lift shift fork and torsion spring from cover.
IMPORTANT: Use appropriate puller or press to re-
move bearings from differential components. Dis-
card all bearings that have been removed and
replace with new bearings during assembly.
13.If necessary, remove bearings (item 12 and 13) from
the output cover and/or differential housing. Discard
bearings after removal.
14.If necessary, remove expansion plugs (item 24) from
output gears.
15.If necessary, remove coupler (item 30) and seal
(item 37) from pinion gear:
A. Use a suitable wrench on coupler to prevent the
coupler and pinion gear from rotating. Remove hex
nut (item 7) that secures coupler to pinion gear.
B. Remove lock washer set (item 8) from pinion gear
(Shown in Fig. 51). For assembly purposes, note that
the wider serrations on the washer halves are orien-
tated against each other.
C. Use suitable puller to remove coupler from pinion
gear.
D. Remove and discard seal from gear case taking
care to not damage case bore during seal removal.
E. Remove O−ring (item 36) from pinion gear. Dis-
card removed O−ring.
NOTE: If the pinion gear (item 10) or bearings (items 14
and 15) are worn or damaged, there probably is consid-
erable damage to other differential components as well.
Replacement of the complete rear differential assembly
would be required.
