DESCRIPTION
The clutch assembly consists of a single dry-disc driven
plate and a one-piece diaphragm spring-type clutch cover. On Wrangler
4-cylinder models, the clutch cover and driven plate diameter is 9.28"
(232 mm). On Wrangler 6-cylinder models, the clutch cover and driven
plate diameter is 10.5" (266 mm). On all other 4 and 6-cylinder
models, the clutch cover and driven plate diameter is 9.7"
(246 mm). The clutch is actuated through a hydraulic master cylinder
and slave cylinder.
On Wrangler models, the slave cylinder is mounted inside the
clutch housing. The bearing is permanently attached to the cylinder
piston.

REMOVAL & INSTALLATION
TRANSMISSION
Removal
1) Remove the shift knob and lock nut from transmission and
transfer case shift levers (if equipped). On Wrangler models, remove
screws attaching transmission and transfer case shift lever boots and
remove both boots.
2) On all other models, raise outer gearshift lever boot and
remove upper part on center console. Remove lower part of console,
remove inner boot and gearshift lever.
3) On Wrangler models, remove transmission shift tower dust
cover. Remove transmission shift lever and stub shaft. DO NOT remove
shift lever from stub shaft.
4) On all models, raise and support vehicle. Drain
transmission lubricant. Mark rear drive shaft for reassembly and
remove rear drive shaft. Support transmission assembly and remove
crossmember. Disconnect speedometer cable and wiring from back-up
light switch.
5) On 4WD models, drain transfer case lubricant. Disconnect
transfer case vacuum hoses and linkage. Tag vacuum hoses for
reassembly. Disconnect front drive shaft and secure out of way.
6) On all models, remove clutch slave cylinder. Position
transmission jack under transmission assembly. Remove bolts securing
clutch housing to engine and remove transmission assembly. Remove
throw-out lever, bearing, and pivot ball from clutch housing.
Installation
To install, reverse removal procedure.

plunger seal faces stem end of plunger. Install stem tip seal so seal
shoulder fits in undercut at end of valve stem.
2) End of valve stem should pass through stem retainer and
seat in small bore in end of plunger. Bend retainer tab downward to
lock stem and retainer on plunger. To complete assembly, reverse
disassembly procedures.
CLUTCH SLAVE CYLINDER
Disassembly
NOTE: On Wrangler models, the integral slave cylinder and throw
out bearing assembly is not serviceable. If cylinder,
bearing or lines become damaged the entire assembly must be
replaced.
1) Clean cylinder exterior. Remove dust boot from cylinder.
Remove cylinder push rod, plunger and spring as an assembly. Remove
spring seal from plunger.
2) Remove snap ring holding push rod in plunger. Remove push
rod and boot. Remove boot from push rod. See Fig. 4. Clean parts with
brake fluid or brake cleaning solvent. Inspect cylinder bore for wear,
nicks or scores. Replace if necessary.

Reassembly
Reverse disassembly procedure. Lubricate cylinder bore and
seal with brake fluid before reassembly.
HYDRAULIC SYSTEM BLEEDING
1) Fill master cylinder reservoir with DOT 3 brake fluid. On
all models except Wrangler, compress slave cylinder plunger by pushing
release lever as far forward as possible.
2) Attach rubber hose to slave cylinder bleeder screw.
Immerse other end of hose in glass container 1/2 full of brake fluid.
Loosen bleeder screw and have an assistant depress clutch pedal.
Tighten bleeder screw and release pedal.
3) Repeat bleeding procedure until fluid entering container
is free of bubbles. DO NOT allow reservoir to run out of fluid during

AXLE SHAFT OVERHAUL
NOTE: All front axle shafts except (Select-Trac) use Cardan "U"
joints and should be overhauled in same manner as drive
shaft "U" joints.
DISASSEMBLY (SELECT-TRAC)
1) Cut and remove both outer boot clamps. Slide boot off
outer CV joint.
2) Using a block of wood seated on inner race, tap joint from
shaft. If shaft is clamped in a vise, be sure to use protective vise
jaws.
3) Tap outer CV cage with a brass punch until cage is tilted
Page 378 of 1378
out far enough to remove first ball bearing. Remove remaining ball
bearings in same manner.
4) Rotate outer CV joint cage outward until it is at a 90
degree angle to installed position. Align 2 oblong holes in outer
joint cage with slots in interior wall of spindle housing and remove
cage and inner race.
5) Remove inner race from cage by aligning shoulder between
race grooves with inside of oblong cage holes. Rotate inner race out
of cage using larger of 2 openings in cage. Remove retaining ring,
spacer ring and outer boot.

CLEANING & INSPECTION
1) Wash all parts in solvent and dry. Inspect inner and outer
ball races for damage. Inspect splined stub shaft for wear, cracks and
twisted splines.
2) Inspect all 6 balls for pitting, cracking or scoring.
Dulling of surface is normal. If any damage is found, replace entire
CV joint assembly. Polished areas in races and on cage spheres are
normal and DO NOT require joint replacement.
REASSEMBLY
1) Apply a light coat of CV grease on ball grooves of inner
and outer races. Install inner race into cage using a rotating action
opposite of removal. Inner race snap ring should face axle side.
2) Be sure ball bearing retaining ring is installed on inner
race side facing small end of cage. Align windows of cage with outer
race lands, and pivot cage with inner race into tilted position
(opposite of removal).
3) Install ball bearings one at a time into outer CV joint as
cage is tilted and rotated. After balls are installed into cage, pivot
cage and inner race into installed position.
4) Slide new seal clamp for small end of boot seal, boot seal
and seal retainer onto axle shaft. Coat inside lip (large diameter end
of seal) with CV grease. Slide seal retainer on end of seal.
5) Spread ears of bearing race snap ring, and slide CV joint
onto axle shaft until snap ring seats in groove. Pack joint with
approximately 1/2 of grease provided in seal kit. Apply remaining
grease inside seal.
6) Slide seal toward joint until small end of seal is in
groove in axle shaft. Position small clamp over small end of seal and
into groove and tighten.
