1988 STEERING
Jeep Steering Columns
All Models
DESCRIPTION
All models use collapsible steering columns. All columns have
integral ignition switch and locking device. Optional tilt wheel is
available with both A/T and M/T. Transmission shift linkage is
integral on all models except those with floor shift.
TROUBLE SHOOTING
Refer to TROUBLE SHOOTING - BASIC PROCEDURES article in the
GENERAL TROUBLE SHOOTING section.
REMOVAL & INSTALLATION
NOTE: Steering column removal and installation procedures refer to
all manufacturers. Not all procedures, however, apply to all
models.
STEERING COLUMN (COLUMN SHIFT)
Removal
1) Disconnect battery negative cable. Disconnect transmission
shift cable rod by prying rod from grommet in shift lever. Remove
cable clip. Remove cable from lower bracket.
2) Disconnect, as equipped, either the flexible coupling,
"Pot" coupling or "U" joint from pinion shaft.
3) Disconnect wiring connectors at column jacket. Remove
steering wheel and horn pad. See STEERING WHEEL & HORN REMOVAL
article. Remove damper assembly (if equipped). On RWD models, remove
turn signal lever.
4) On all models, remove steering column-to-floor pan
attaching screws. Expose steering column bracket. Remove instrument
panel steering column cover. Lower reinforcement. Disconnect bezel.
Remove indicator set screw and gearshift pointer from shift housing.
5) Remove steering column bracket-to-instrument panel
attaching nuts. Lower support bracket. Firmly grasp steering column
assembly and pull rearward while disconnecting lower stub shaft from
pinion shaft coupling.
NOTE: On vehicles equipped with cruise control and M/T, take care
not to damage clutch pedal cruise control switch.

Fig. 1: Exploded View of RWD Steering Column Major Assemblies
Installation
1) On all models, aligning lower shaft with lower coupling
and insert shaft. Raise column assembly into position onto studs.
Loosely install nuts and washers in breakaway capsules. Pull column
rearward. Tighten nuts to specification. See TORQUE SPECIFICATIONS.
2) Install a new shift lever grommet using pliers and back-up
washer to snap the grommet into place. Use a multipurpose grease to
aid installation.
3) Connect gearshift cable rod to shift lever by snapping rod
into grommet with pliers. Adjust linkage. Place steering wheel on
shaft with master splines aligned. Place damper assembly inside
steering wheel (if equipped). Install steering wheel retaining nut.
Tighten to 45 ft. lbs. (61 N.m).
4) Install horn pad assembly. Refer to procedures in the
STEERING WHEEL & HORN REMOVAL article. Connect wiring connectors at
steering column jacket. Connect battery negative cable. Test operation
of lights and horn.
5) On models with A/T, install gearshift indicator pointer.
Slowly move gearshift lever from "LOW" position to "PARK" position,
pausing briefly at each selector position. Loosen and readjust to
align pointer with each position (if necessary). Install instrument
panel steering column cover.
STEERING COLUMN (FLOOR SHIFT)
The steering column with a floor mounted gearshift is
basically the same as previously described. Standard columns and
service procedures are identical except as described below.
* In place of rotating shift housing, there is a plastic shroud
which is fixed to lock housing. Shroud covers jacket and lock
inhibitor assembly. It is held in place by a tab that fits
under side cover and one screw. Shroud can only be replaced
by removing lock housing from jacket.

* The lock inhibitor assembly consists of a lever that engages
lock levers (preventing locking of steering shaft), a button
to operate lever and a return spring. Assembly is attached to
lock housing in same location as shift gate is on column
shift. Lower steering shaft bearing is mounted in an aluminum
support.
* A spring is attached between shift housing and column jacket.
This spring keeps housing rotated counterclockwise against
rubber bumper.
OVERHAUL
