Jeep Wrangler TJ. Manual — part 526
REAR OUTPUT SHAFT SEAL
REMOVAL
(1) Shift the transmission and transfer case into
NEUTRAL.
(2) Raise and support vehicle.
(3) Mark a line across the pinion shaft and at each
end of the propeller shaft for installation reference.
(4) Remove the U-joint strap bolts at the pinion
shaft yoke.
(5) Pry open clamp holding the dust boot to propel-
ler shaft yoke (Fig. 87).
(6) Slide the slip yoke off of the transmission/
transfer case output shaft and remove the propeller
shaft.
(7) Spread band clamp which holds output shaft
boot to the output shaft slinger, or output shaft
damper, with a suitable awl, or equivalent.
NOTE: Vehicles built with a 4.0L engine and a man-
ual transmission use a damper weight on the trans-
fer case output shaft. Be sure to identify the
transfer case before proceeding.
(8) Remove output shaft boot from slinger, or out-
put shaft damper, and output shaft.
(9) If the vehicle is not equipped with an output
shaft damper, remove the output shaft rear slinger
using Puller MD-998056-A (Fig. 88).
(10) If the vehicle is equipped with an output shaft
damper, use Screws 8421 and the puller yoke and
forcing screw from a bolt-grip puller set, such as
those used to remove steering wheels and harmonic
balancers, to remove the transfer case output shaft
damper.
(11) Use a suitable pry tool, or a slide hammer
mounted screw, to remove the seal from the rear
retainer (Fig. 89).

INSTALLATION
(1) Apply liberal quantity of petroleum jelly to new
rear seal and to output shaft. Petroleum jelly is
needed to protect seal lips during installation.
(2) Slide seal onto Seal Protector 6992 (Fig. 90).
Slide seal protector and seal onto output shaft.
(3) Slide Installer C-4076-B onto seal protector
with the recessed side of the tool toward the seal.
Drive seal into rear bearing retainer with Installer
C-4076-B and Handle MD-998323 (Fig. 91).
NOTE: Vehicles built with a 4.0L engine and a man-
ual transmission use a damper weight on the trans-
fer case output shaft. Be sure to identify the
transfer case before proceeding.
(4) Install a new output shaft rear slinger with
Installer 8408, if the vehicle is not equipped with an
output shaft damper.
(5) If the vehicle is equipped with an output shaft
damper, install the output shaft damper as follows:
(a) Position the damper weight on the output
shaft. Start the damper onto the output shaft
chamfer, being careful to keep the weight square to
the output shaft. (Fig. 92)
(b) Position the driver portion of Installer 8422
(Fig. 93) onto the damper, making sure the legs of
the damper are positioned through the slots of the
damper.

(c) Thread the puller screw of Installer 8422 into
the output shaft by hand only. Make sure the
screw is fully threaded into the output shaft.
(d) Using a wrench to hold the pulling screw sta-
tionary (Fig. 94), turn the pulling screw nut until
the driver legs contact the rear face of the transfer
case rear retainer. When the legs contact the
retainer, the damper is properly positioned on the
output shaft.
(6) Install boot on output shaft slinger, or output
shaft damper, and crimp retaining clamp with tool
C-4975-A (Fig. 95).
(7) Slide the slip yoke on the transmission/transfer
case output shaft. Align installation reference marks
at the axle yoke and install the propeller shaft.
(8) Tighten the U-joint strap/clamp bolts at the
axle yoke to 19 N·m (14 ft. lbs.).
(9) Crimp clamp with Clamp Tool C-4975A to hold
dust boot to propeller shaft yoke.
(10) Remove support and lower the vehicle.
SHIFT LEVER
REMOVAL
(1) Shift transfer case into 4L.
(2) Raise vehicle.
(3) Loosen adjusting trunnion locknut and slide
shift rod out of trunnion (Fig. 96). If rod lacks
enough travel to come out of trunnion, push trunnion
out of torque shaft.
(4) Lower vehicle.
(5) Remove console. (Refer to 23 - BODY/INTERI-
OR/FLOOR CONSOLE - REMOVAL)
(6) Remove screws attaching lever assembly to
floorpan and remove assembly and shift rod (if left
attached).
INSTALLATION
(1) If shift rod was not removed from lever assem-
bly, work rod down through floorpan opening. Then
position lever assembly on floorpan and install
assembly attaching screws.
(2) Install console. (Refer to 23 - BODY/INTERI-
OR/FLOOR CONSOLE - INSTALLATION)
(3) Raise vehicle.
(4) Connect trunnion to torque shaft arm. Or, slide
shift rod into trunnion on range lever. Be sure shift
rod slides freely in trunnion.
(5) Verify that range lever is in 4L position. Then
tighten trunnion lock bolt.
(6) Lower vehicle and check transfer case shift
operation.
