ball stud and release fork with high temp grease.
Then install release bearing, fork and retainer clip.
(3) Mount transmission on transmission jack.
(4) Lightly lubricate pilot bearing and transmis-
sion input shaft splines with Mopar high temp
grease.
(5) Align transmission input shaft, release bearing,
and clutch disc splines. Then slide transmission into
place.
(6) Install and tighten clutch housing-to-engine
bolts to 38 Nzm (28 ft. lbs.) torque.Be sure the
housing is properly seated on engine block be-
fore tightening bolts.
(7) Lower transmission approximately 7-8 cm (3
in.) for access to shift tower. Be sure transmission is
in first or third gear.
(8) Reach up and around transmission and insert
shift lever in shift tower. Press lever retainer down-
ward and turn it clockwise to lock it in place. Then
install lever dust boot on shift tower.
(9) Install slave cylinder in clutch housing.
(10) Align and install transfer case on and trans-
mission. Tighten transfer case-to-transmission nuts
to 35 Nzm (26 ft. lbs.) torque.
(11) Connect transfer case vent hose and shift link-
age. Check and adjust linkage if necessary.
(12) Connect transfer case vent hose.
(13) Secure wire harnesses in clips/tie straps on
transmission and transfer case.
(14) Connect backup light switch wires.
(15) Connect vehicle speed sensor wires.
(16) Install and connect crankshaft position sensor.
(17) Install rear crossmember (Fig. 5). On XJ,
tighten crossmember-to-frame bolts to 41 Nzm (31 ft.
lbs.) torque. Then tighten transmission-to-rear sup-
port bolts/nuts to 45 Nzm (33 ft. lbs.) torque. On YJ,
tighten bolts/nuts to indicated torque (Fig. 5).
(18) Remove jack stand.
(19) Align and install front/rear propeller shafts.
Tighten shaft U-joint clamp bolts to 19 Nzm (170 in.
lbs.) torque.
(20) Install skid plate, if equipped. Tighten bolts to
42 Nzm (31 ft. lbs.) torque. Tighten stud nuts to 17
Nzm (150 in. lbs.) torque.
(21) Top off transmission and transfer case lubri-
cant levels.
(22) Lower vehicle.

ADAPTER HOUSING AND FRONT BEARING
RETAINER REMOVAL
(1) Drain transmission lubricant.
(2) Remove release bearing and lever.
(3) Remove clutch housing bolts and remove hous-
ing.
(4) On 2-wheel drive models, remove vehicle speed
sensor, speedometer adapter and speedometer driven
gear. Then remove extension housing seal (Fig. 1).
(5) Remove detent spring and ball. Remove detent
plug (Fig. 2) and remove detent spring and ball with

(6) Remove shift arm set bolt (Fig. 3) and remove
bolt and lockplate.
(7) Remove shift lever shaft plug (Fig. 4). Then
pull shaft out with large magnet.
(8) Remove adapter housing bolts.
(9) Remove adapter housing by tapping it loose
with plastic mallet.
(10) Remove front bearing snap rings (Fig. 5).(11) Remove front bearing retainer and intermedi-
ate plate by tapping them loose with plastic mallet
(Fig. 6).
SHIFT MECHANISM DISASSEMBLY
(1) Install two clutch housing bolts and spare
washers in intermediate plate (Fig. 7). Then clamp
plate and gear assembly in vise.Use enough wash-
ers to prevent bolts from touching. Also be sure
vise jaws are clamped on bolt heads (Fig. 7).
