Chrysler PT Cruiser. Manual — part 752
(6) Thread the wheel retaining bolt back into the
end of the shaft until approximately 13 mm (0.5 in.)
of thread is showing between the wheel and the head
of the bolt.
(7) Install a steering wheel puller on the steering
wheel.
CAUTION: Do not bump or hammer on steering
wheel or steering column shaft when removing
steering wheel from steering column.
(8) While holding the steering wheel firmly in the
STRAIGHT-AHEAD position, remove steering wheel
from the steering column shaft using the puller.
(9) Remove the wheel retaining bolt and the steer-
ing wheel. Take care to feed the wires gently through
the holes in the steering wheel.
INSTALLATION
(1) Confirm that:
(a) The front wheels are in the STRAIGHT-
AHEAD position.
(b) The turn signal stalk is in the neutral posi-
tion.
(2) Ensure the three foam rubber driver airbag
retaining clip pads are still in place on the rear of
the steering wheel (Fig. 40). Replace any missing
pads.
CAUTION: Do not install the steering wheel onto the
shaft of the steering column by driving it onto the
shaft.
(3) Feed the clockspring wiring leads through the
hole in the steering wheel. Align the steering wheel’s
wide mounting spline with the steering column shaft
missing spline area and push the wheel onto the
shaft. Make sure the clockspring lines up with the
back of the wheel and does not bind.
(4) Install the steering wheel retaining bolt and
tighten it until the steering wheel is fully installed
on shaft. Tighten the steering wheel retaining bolt to
54 N·m (40 ft. lbs.) torque.
(5) Install the driver airbag. (Refer to 8 - ELEC-
TRICAL/RESTRAINTS/DRIVER AIRBAG - INSTAL-
LATION)
WARNING: DO NOT CONNECT BATTERY NEGATIVE
CABLE YET. REFER FIRST TO AIRBAG SYSTEM
TEST. (Refer to 8 - ELECTRICAL/RESTRAINTS -
DIAGNOSIS AND TESTING)
(6) Reconnect battery using Airbag System Test
procedure in Restraints. (Refer to 8 - ELECTRICAL/
RESTRAINTS - DIAGNOSIS AND TESTING)
(7) Close hood.
(8) Verify vehicle and system operation.

GEAR
DESCRIPTION
The power steering gear is the rack-and-pinion
type. It is mounted on the front suspension cross-
member (Fig. 1). The outer ends of the outer tie rods
attach to the steering knuckles.
NOTE: The power steering gear should not be ser-
viced or adjusted. If a malfunction or oil leak occurs
with the steering gear, the complete steering gear
needs to be replaced.
OPERATION
Turning of the steering wheel is converted into lin-
ear (side-to-side) travel through the meshing of the
helical pinion teeth with the rack teeth in the steer-
ing gear. This travel pushes and pulls the tie rods to
change the direction of the vehicle’s front wheels.

Power assist steering provided by the power steer-
ing pump is controlled by an open-center, rotary type
control valve which directs fluid from the pump to
either side of the integral rack piston upon demand.
Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. As required
steering effort increases, as in a turn, the torsion bar
twists, causing relative rotary motion between the
rotary valve body and the valve spool. This move-
ment directs oil behind the integral rack piston
which, in turn, builds up hydraulic pressure and
assists in the turning effort.
Manual steering control of the vehicle can be main-
tained if power steering assist is lost. However,
under this condition, steering effort is significantly
increased.
REMOVAL
REMOVAL
NOTE: Before proceeding, (Refer to 19 - STEERING
- WARNING).
(1) Place the steering wheel in the STRAIGHT-
AHEAD position. Using a steering wheel holder, lock
the steering wheel in place to keep it from rotating
(Fig. 2). This keeps the clockspring in the proper ori-
entation.
(2) Remove the silencer pad below the knee
blocker panel below the steering column.
(3) Fold down and remove the knee blocker.
(4) Remove the steering column coupling retainer
pin, back off the pinch bolt nut, and remove the
steering column coupling pinch bolt (Fig. 3) (the
pinch bolt nut is caged to the coupling and is not
removable). Separate the upper and lower steering
column couplings.
(5) Raise the vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(6) Remove both front tire and wheel assemblies
from the vehicle.
(7) Remove nuts attaching both outer tie rods to
the steering knuckles (Fig. 4). Remove each nut by
holding the tie rod stud stationary while loosening
and removing the nut with a crowfoot wrench (or
open-end wrench).
(8) Remove the outer tie rods from the steering
knuckles using Remover, Special Tool MB991113
(Fig. 5).
(9) Remove the tie rod heat shields.

(10) On vehicles equipped with a power steering
fluid pressure switch, release the locking tab on the
wiring harness connector for the power steering fluid
pressure switch, then remove the wiring harness con-
nector from the power steering fluid pressure switch
(Fig. 6).
(11) Back out the tube nut securing the power
steering fluid pressure hose to the gear (Fig. 7) (Fig.
8).
(12) Disconnect the cooler or return hose at the
power steering gear outlet port fitting (Fig. 7) (Fig.
8).
(13) On
vehicles
equipped
with
crossmember
mounted power steering fluid coolers:
(a) Remove the cooler tube from the right rout-
ing clip.
(b) Remove the two screws securing the cooler to
the front suspension crossmember (Fig. 7). Allow
the cooler to hang out of the way.
