should now slide freely in trunnion.
(6) Verify that transfer case range lever is in 4L posi-
tion.

ver (Fig. 5). Then tighten trunnion lock bolt.
(8) Lower vehicle.
(9) Remove shift lever spacer and install bezel.

(2) Raise vehicle.
(3) Drain transfer case lubricant.
(4) Mark front and rear propeller shaft yokes for
alignment reference.
(5) Place support stand under transmission.
(6) Remove rear crossmember.
(7) Disconnect front/rear propeller shafts at trans-
fer case.
(8) Disconnect vehicle speed sensor wires and re-
move sensor and adapter assembly if necessary.
(9) Disconnect transfer case shift rod from range lever.
(10) Disconnect transfer case vent hoses and elec-
trical switch connector.
(11) Support transfer case with transmission jack.
(12) Remove bolts attaching the transfer case to
transmission.
(13) Secure transfer case to jack with chains.(14) Pull transfer case and jack rearward to disen-
gage transfer case.
(15) Remove transfer case from under vehicle.
TRANSFER CASE INSTALLATION
(1) Mount transfer case on transmission jack. Se-
cure transfer case to jack with safety chains.
(2) Position transfer case under vehicle.
(3) Align transfer case and transmission shafts and
install transfer case on transmission.
(4) Install and tighten transfer case attaching nuts
to 35 Nzm (26 ft. lbs.) torque.
(5) Install vehicle speed sensor and adapter, if re-
moved. Then connect vehicle speed sensor wires, vent
hoses and electrical switch connector.
(6) Align and connect propeller shafts. Tighten shaft
U-joint clamp bolts to 19 Nzm (14 ft. lbs.) torque.
(7) Fill transfer case with recommended automatic
transmission fluid.
(8) Install rear crossmember. Tighten crossmember
bolts to 41 Nzm (30 ft. lbs.) torque.
(9) Remove transmission jack and transmission
support stand.
(10) Connect transfer case range lever to shift rod.
(11) Check and adjust transfer case shift linkage if
necessary.
(12) Lower vehicle.

Inspect the differential gears, thrust washers and
case halves. Replace the mainshaft gear if the gear
teeth or the brass ring on the underside of the gear
are damaged. Replace the differential as an assembly
if the gears, case halves, or the pins in the lower case
half are damaged.
Inspect the case halves, extension housing and re-
tainers for cracks, porosity, or damaged sealing sur-
faces. Inspect the shafts, gears, chain and shift
components for wear or damage.
Inspect all of the transfer case bearings for wear,
roughness, pitting, or galling. Replace worn or dam-
aged bearings as outlined in the assembly section.
TRANSFER CASE ASSEMBLY
(1) Lubricate the transfer case components with
automatic transmission fluid or petroleum jelly
(where indicated) during assembly.
CAUTION: The bearing bores in various transfer
case components contain oil feed holes. Be sure re-
placement bearings do not block these feed holes.
(2) Remove the front output shaft, front bearing
snap ring (Fig. 42).(3) Remove the old bearing and install the new
bearing with a driver handle and installer tool (Fig.
43).
(4) Install the front bearing snap ring (Fig. 42).
(5) Install new front output shaft oil seal (Fig. 44).

(11) Assemble low range gear, input gear thrust
washers, input gear and input gear retainer (Fig. 49).
(12) Install low range gear snap ring (Fig. 50).
(13) Lubricate input gear and low range gears with
automatic transmission fluid.
(14) Start the input gear shaft into the front case
bearing.
(15) Press the input gear shaft into the front bear-
ing.CAUTION: Be sure the input gear installer tool is
the proper size. The wrong size tool could push the
input gear pilot bearing too far into the gear bore
(Fig. 51). Also, do not press against the end sur-
faces of the low range gear. The gear case and
thrust washers could be damaged.
(16) Install new input gear snap ring (Fig. 52).

(24) Position low range fork and hub in case. Be
sure low range fork pin is engaged in the shift sector
slot (Fig. 57).
(25) Lubricate differential components with auto-
matic transmission fluid.
(26) Install sprocket gear in differential bottom
case (Fig. 58).(27) Install differential planet gears and new
thrust washers (Fig. 59).Be sure thrust washers
are installed at top and bottom of each planet
gear.
(28) Install differential mainshaft gear (Fig. 59).
(29) Align and position differential top case on bot-
tom case (Fig. 60). Align using scribe marks made at
disassembly.
