SERVICE INFORMATION
The steering linkage consists of a pitman arm, drag
link, tie rod, and steering damper. Adjustment
sleeves are used on the tie rod and drag link for toe
and steering wheel alignment.
Refer to Group 2, Front Suspension and Axle for
additional information.The tie-rod end ball stud seals should be inspected
during all oil changes.
A damaged ball stud seal requires removal of the
seal. Inspect the tie-rod end ball stud at the throat
opening. Check for lubricant loss, contamination, ball
stud wear or corrosion. If these conditions exist, re-
place the tie-rod. A replacement seal can be installed
if lubricant is in good condition. Otherwise, a com-
plete replacement ball stud end should be installed.
Lubricate the tie-rod end with MOPARtMulti-Mile-
age Lubricant, or equivalent product.
Use Puller C-3894-A for tie rod removal. Fail-
ure to use this tool could damage the ball stud
and seal (Fig. 1).
TIE ROD
REMOVAL
(1) Remove the cotter pins and nuts at the steering
knuckles and drag link (Fig. 2). Remove the steering
damper from the tie rod.
(2) Loosen the ball studs with a puller tool to re-
move the tie rod.

SERVICE INFORMATION
A recirculating-ball steering gear is used with the
power (assisted) steering system (Fig. 1). The power
steering gear can be adjusted and internally serviced.
Discard all O-ring seals during disassembly,
they are not re-usable.Safety goggles should be worn at all times
when involved with power steering gear or
pump service.

1/2 the total number of turns. This is the center of
the gear travel (Fig. 12).
(3) Turn the pitman shaft adjuster screw back
(COUNTERCLOCKWISE) until extended, then turn
back in (CLOCKWISE) one full turn.
(4) Place the torque wrench in the vertical position
on the stub shaft. Rotate the wrench 45 degrees each
side of the center and record the highest rotational
torque on center (Fig. 13).
(5) Turn the adjuster in until torque to turn stub
shaft is 0.6 to 1.2 Nzm (6.0 to 10.0 in. lbs.) more than
reading in Step 4.
(6) Prevent the adjuster screw from turning while
tightening adjuster lock nut. Tighten the adjuster
lock nut to 49 Nzm (36 ft. lbs.).
GEAR DISASSEMBLY INFORMATION
CAUTION: Cleanliness is extremely important when
repairing a power steering gear. Keep the bench,
tools and components clean at all times. Thor-
oughly clean the exterior of the gear with cleaning
solvent before disassembly. Drain as much of the
fluid as possible. Use protective vise jaws at all
times when clamping components. During assem-
bly, lubricate all components with power steering
fluid except where noted (Fig. 14).
