(
1) - SAE 10W-30 SH/CD is preferred. 

(
2) - Add 4 ozs. (118 ml) of Limited-Slip differential lubricant 

additive when changing fluid. 

(
3) - For vehicles operating under heavy-duty towing conditions, 

use SAE 75W-140 Synthetic lube. 

NOTE: Before using SAE 75W-140 Synthetic the old fluid must 

be DRAINED and FLUSHED with clean mineral based axle 

lubricant. Then refill with new synthetic lube. 

(
4) - Use low pressure grease gun to prevent seal damage. 

(
5) - Fill until lubricant squeezes out from the base of seals. 

(
6) - Fill ball joint until seal starts to swell.

2) Ensure sector shaft cover bolts are tightened to
specification. Using an INCH lb. torque wrench, measure highest torque
required to rotate steering wheel back and forth through the center
position. Meshload must be adjusted if not within specification. See
the MESHLOAD SPECIFICATIONS table.

Application INCH Lbs. (N.m)
Cherokee, Comanche & Wrangler .......... ( 1) 4-10 (.5-1.1)
( 1) - In excess of worm bearing preload. Maximum preload is

3) Loosen sector shaft adjuster screw lock nut. Adjust sector
shaft adjuster screw to obtain correct reading. Tighten lock nut to
specification while holding adjusting screw.
4) Reverse removal procedures for components removed. Ensure
reference mark is aligned on pitman arm and sector shaft. Tighten
pitman arm retaining nut to specification. On Jeep models, stake
pitman arm retaining nut in 2 places.
REMOVAL & INSTALLATION
STEERING GEAR
CAUTION: All steering component fasteners are made of special quality
materials. Replacement fasteners must be of same part number
or equivalent. Tighten all fasteners to proper torque.
Install new cotter pin where used.
Removal
1) Disconnect negative battery cable. Set front wheels in
straight-ahead position. Note position of steering wheel. Remove
flexible coupling shield retaining screw (if equipped).
2) Remove flexible coupling-to-steering worm shaft flange
bolts or lower universal joint pinch bolt. Remove sector shaft nut and
washer. Place reference mark in relation of pitman arm-to-sector
shaft. Using Puller (J-6632-01), remove pitman arm. Remove steering
gear-to-frame bolts. Remove steering gear.
Installation
1) Install flexible coupling on worm shaft. Align flat on
coupling with flat on worm shaft. Push coupling on shaft until shaft
touches shoulder. Install pinch bolt. Pinch bolt must pass through
shaft undercut.
2) To install remaining components, reverse removal
procedure. Align reference mark on pitman arm and sector shaft. Ensure
splines are properly aligned. Tighten bolts to specification. On Jeep
models, stake sector shaft nut in 2 areas.
SECTOR SHAFT SEAL
NOTE: On some models, sector shaft seal may be replaced without
removing steering box. It may be necessary to remove
steering gear to gain access to remove sector shaft seal.
Removal & Installation
1) Place steering gear at center of travel. Remove sector
