POWER STEERING PUMPÐINITIAL OPERATION
CAUTION: The fluid level should be checked with
engine off to prevent injury from moving compo-
nents. Use only Mopar Power Steering Fluid. Do not
use automatic transmission fluid. Do not overfill.
Wipe filler cap clean, then check the fluid level.
The dipstick should indicate FULL COLD when the
fluid is at normal temperature 21ÉC to 27ÉC (70ÉF to
80ÉF).
(1) Fill the pump fluid reservoir to the proper level
and let the fluid settle for at least two (2) minutes.
(2) Start the engine and let run for a few seconds.
Then turn the engine off.
(3) Add fluid if necessary. Repeat the above proce-
dure until the fluid level remains constant after run-
ning the engine.
(4) Raise the front wheels off the ground.
(5) Start the engine. Slowly turn the steering
wheel right and left, lightly contacting the wheel
stops.
(6) Add power steering fluid if necessary.
(7) Lower the vehicle and turn the steering wheel
slowly from lock to lock.
(8) Stop the engine. Check the fluid level and refill
as required.
(9) If the fluid is extremely foamy, allow the vehi-
cle to stand a few minutes and repeat the above pro-
cedure.

SERVICE INFORMATION
The steering linkage consists of a pitman arm, drag
link, tie rod, and steering dampener. 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 a Puller tool for tie rod removal. Failure
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 tie rod
ball studs and drag link (Fig. 2).
(2) Loosen the ball studs with a puller tool to re-
move the tie rod.
(3) If necessary, loosen the end clamp bolts and re-
move the tie rod ends from the tube.
INSTALLATION
(1) If necessary, install the tie rod ends in the tube
(Fig. 2). Position the tie rod clamp as shown (Fig. 3)
and tighten to 27 Nzm (20 ft. lbs.) torque.
(2) Install the tie rod on the drag link and steering
knuckle. Install the retaining nuts.
(3) Tighten the ball stud nut on the steering
knuckle to 47 Nzm (35 ft. lbs.) torque. Tighten the
ball stud nut to drag link to 75 Nzm (55 ft. lbs.)
torque. Install new cotter pins.
DRAG LINK
REMOVAL
The drag link ball stud cannot be disassem-
bled for service.
(1) Remove the steering dampener ball stud from
the drag link with a puller tool.
(2) Remove the drag link from the steering knuckle
with a puller tool. Remove the same for tie rod and
pitman arm.
(3) If necessary, loosen the end clamp bolts and re-
move the tie rod end from the link.
INSTALLATION
(1) Install the drag link adjustment sleeve and tie
rod end. Position clamp bolts as shown (Fig. 3).
(2) Position the drag link at the steering linkage
(Fig. 2).
Install the nut that attach the drag link to the
steering knuckle. Do the same for the tie rod and pit-
man arm.
(3) Tighten the nut at the steering knuckle to 47
Nzm (35 ft. lbs.) torque. Tighten the pitman and tie
rod ball stud nuts to 75 Nzm (55 ft. lbs.) torque. In-
stall new cotter pins.

Tighten the nut to 75 Nzm (55 ft. lbs.) torque. Install
a new cotter pin.
PITMAN ARM
REMOVAL
(1) Remove the cotter pin and nut from the drag
link at the pitman arm.
(2) Remove the drag link ball stud from the pit-
man arm with a puller.
(3) Remove the nut and washer from the steering
gear shaft. Mark the pitman shaft and pitman arm
for installation reference. Remove the pitman arm
from steering gear with Puller 7998 or C-4150 (Fig.
4).
