SERVICE INFORMATION
The power steering pump internal components are
not serviced or adjusted. If a malfunction or an inter-
nal fluid leak occurs, the complete unit must be re-
placed. A reservoir, cap, and O-ring seal kit are the
only service components available.
PRESSURE AND RETURN HOSE REPLACEMENT
Cap hose open ends and pump/steering gear fit-
tings to prevent entry of foreign material.
WARNING: POWER STEERING FLUID (AND PUMP
COMPONENTS) AND THE EXHAUST SYSTEM CAN
BE EXTREMELY HOT IF THE ENGINE HAS BEEN
RECENTLY OPERATING. DO NOT START THE EN-
GINE WITH ANY LOOSE OR DISCONNECTED
HOSES. DO NOT ALLOW THE HOSES TO TOUCH A
HOT EXHAUST MANIFOLD OR THE CATALYTIC
CONVERTER.
REMOVAL

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.

Drag Link............................... 16
Pitman Arm.............................. 17
Service Information........................ 16Steering Damper.......................... 17
TieRod ................................ 16
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 a Puller tool C-3894-A for tie rod removal.
Failure to use this tool could damage the ball
stud and seal (Fig. 1).
