ASSEMBLY
Refer to Figure 15, next page.
NOTE: Brake Assembly, and optional Re-
turn to Neutral have to be re moved be fore
the fol low ing steps can be per formed.
DISASSEMBLY
1. Remove the axle hub assembly (118) on con trol
side by re mov ing nuts (119), and hub as sem-
blies (118).
2. Remove the eight torx head screws (80) that
secure the R.H. hous ing assembly (2).
3. Remove R.H. housing assembly (2), while
holding axle shaft (76) in place.
4. Remove the two housing pins (117).
5. Remove washer (71) from axle shaft (76).
6. Re
move spur gear (60), and thrust plate
(62).
7. Remove 21T sun gear (61), and sleeve bear ing
(96).
8. Remove the planetary gears (59).
9. Remove washer (70), and axle shaft (76).
10. Remove the four carrier pins (58) from plan-
e tary car ri er (64).
11. Remove 51T ring gear (63) from main hous ing
(1).
12. Remove the two miter gears (66), and dif fer-
en tial shaft (67).
13. Remove planetary carrier (64) and dif fer en tial
thrust plate (68).
14. If necessary, remove the second axle shaft
assembly (76) from main hous ing (1).
15. Remove the seal from the shaft, if necessary.
INSPECTION
1. Inspect all gears for excessive wear or dam age
and re place if necessary.
2. Remove all sealant from both hous ings and
in spect seal lands for damage when clean-
ing.
3. If miter gear (65) needs re placed, remove jam
nut (73) from axle shaft (76).
ASSEMBLY
1. If necessary, install L.H. Axle shaft assembly
(76) into main hous ing (1). If necessary, re as-
sem ble axle shaft assembly (76) by in stall ing
wash er (70), miter gear (65), and jam nut (73)
onto axle shaft (76).
2. Install differential thrust plate (68) into main
housing (1).
3. Install planetary carrier (64) into main hous ing
(1).
4. Reassemble the two miter gears (66) onto dif-
ferential shaft (67), and install assembly into
planetary carrier (64).
5. Install 51T ring gear (63) into main housing
(1).
6. Install the four carrier pins (58) into planetary
carrier (64).
7. If necessary, re as sem ble axle shaft as sem bly
(76) by in stall ing washer (70), miter gear (65),
and jam nut (73) onto axle shaft (76).
8. Install R.H. Axle shaft assembly (76) partway
into as sem bled differential components.
NOTE: It will be necessary to support the RH
axle shaft in the partially installed position
while steps 9 through 16 are completed.
9. Assemble sleeve bearing (96) and sun gear
(61), slid ing them onto R.H. axle shaft. The
smaller diameter on the sun gear OD should
be “IN”.
10. Install the four 15T planetary gears (59) on
pins (80) . Make sure the planetary gears are
properly aligned with the sun gear. Mate the
bevel gear on the end of the R.H. axle shaft
with the bevel gears in the differential assem-
bly. Continue to support the R.H. axle shaft.
