GEAR
DESCRIPTION
A rack and pinion steering gear (Fig. 1) is made up
of two main components, the pinon shaft and the
rack. The gear cannot be adjusted or internally ser-
viced. If a malfunction or a fluid leak occurs, the gear
must be replaced as an assembly.
OPERATION
The steering column intermediate shaft is attached
to the gear pinion. The rotation of the pinion moves
the gear rack from side-to-side. This lateral action of
the rack pushes and pulls the tie rods, which are
connected to the steering knuckles to change the
direction of the front wheels.

PUMP
DESCRIPTION
Hydraulic pressure for the power steering system
is provided by a belt driven power steering pump
(Fig. 1). The pump shaft has a pressed-on high
strength plastic drive pulley that is belt driven by
the crankshaft pulley. The integral reservoir used on
the 3.7L only is attached to the pump body with
spring clips (Fig. 1). The 2.4L uses a remote fluid res-
ervoir (Fig. 2). The power steering pump is connected
to the steering gear by the pressure and return
hoses.
OPERATION
The power steering pump is a constant flow rate
and displacement, vane-type pump. The pump inter-
nal parts operate submerged in fluid. The flow con-
trol orifice is part of the high pressure line fitting.
The pressure relief valve inside the flow control valve
limits the pump pressure.Fig. 1 POWER STEERING PUMP ASSEMBLY

NOTE: Power steering pumps have different pres-
sure rates and are not interchangeable with other
pumps.
STANDARD PROCEDURE - POWER STEERING
PUMP - INITIAL OPERATION
WARNING: THE FLUID LEVEL SHOULD BE
CHECKED WITH ENGINE OFF TO PREVENT INJURY
FROM MOVING COMPONENTS.
CAUTION: Use MOPAR Power Steering Fluid or
equivalent. Do not use automatic transmission fluid
and do not overfill.
Wipe filler cap clean, then check the fluid level.
The dipstick should indicateCOLDwhen the fluid is
at normal ambient temperature.
(1) Fill the pump fluid reservoir to the proper level
and let the fluid settle for at least two minutes.
(2) Raise the front wheels off the ground.
(3) Slowly turn the steering wheel right and left,
lightly contacting the wheel stops at least 20 times.
(4) Check the fluid level add if necessary.
(5) Lower the vehicle, start the engine and turn
the steering wheel slowly from lock to lock.
(6) Stop the engine and check the fluid level and
refill as required.
CAUTION: Do not run a vehicle with foamy fluid for
an extended period. This may cause pump damage.
(7) If the fluid is extremely foamy or milky look-
ing, allow the vehicle to stand a few minutes and
repeat the procedure.
(8) Add fluid if necessary. Repeat the above proce-
dure until the fluid level remains constant after run-
ning the engine.
REMOVAL
