shaft CHRYSLER CARAVAN 2002 Service Manual

WARNING: THE AIR BAG SYSTEM IS A SENSITIVE,
COMPLEX ELECTRO-MECHANICAL UNIT. BEFORE
ATTEMPTING TO DIAGNOSE, REMOVE OR INSTALL
THE AIR BAG SYSTEM COMPONENTS YOU MUST
FIRST DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE. THEN WAIT TWO
MINUTES FOR THE SYSTEM CAPACITOR TO DIS-
CHARGE. FAILURE TO DO SO COULD RESULT IN
ACCIDENTAL DEPLOYMENT OF THE AIR BAG AND
POSSIBLE PERSONAL INJURY. THE FASTENERS,
SCREWS, AND BOLTS, ORIGINALLY USED FOR
THE AIR BAG COMPONENTS, HAVE SPECIAL
COATINGS AND ARE SPECIFICALLY DESIGNED
FOR THE AIR BAG SYSTEM. THEY MUST NEVER
BE REPLACED WITH ANY SUBSTITUTES. ANYTIME
A NEW FASTENER IS NEEDED, REPLACE WITH
THE CORRECT FASTENERS PROVIDED IN THE
SERVICE PACKAGE OR FASTENERS LISTED IN
THE PARTS BOOKS.
WARNING: SAFETY GOGGLES SHOULD BE WORN
AT ALL TIMES WHEN WORKING ON STEERING
COLUMNS.
CAUTION: Disconnect negative (ground) cable from
the battery before servicing any column compo-
nent.
CAUTION: Do not attempt to remove the pivot pins
to disassemble the tilting mechanism. Damage will
occur.

DESCRIPTION - IGNITION INTERLOCK
All vehicles equipped with automatic transaxles
have an interlock system. The system prevents shift-
ing the vehicle out of Park unless the ignition lock
cylinder is in the Unlock, Run or Start position. In
addition, the operator cannot rotate the key to the
lock position unless the shifter is in the park posi-
tion. On vehicles equipped with floor shift refer to
the - Transaxle for Automatic Transmission Shifter/
Ignition Interlock.

umn or steering column shaft when removing steer-
ing wheel from steering column shaft.CAUTION: When installing steering wheel puller
bolts in steering wheel, (Fig. 40) do not thread bolt
into steering wheel more than a half inch. If bolts
are threaded into the steering wheel more than a
half inch they will contact and damage the clock-
spring.

INSTALLATION
CAUTION: Do not force steering wheel onto steer-
ing column shaft by driving it on. Pull steering
wheel down onto shaft using only the steering
wheel retaining nut.
(1) Align master splines on steering wheel and
steering shaft, and flats on steering wheel with for-
mations on clockspring. Install the steering wheel on
the steering column shaft. All wiring leads from the
clockspring must be routed as shown (Fig. 41).NOTE: Before installing the damper on the steering
wheel, inspect the damper to ensure the rubber iso-
lator on the damper is not deteriorated or damaged.
If the damper is installed with a damaged isolator a
buzz, squeak or rattle condition may develop.
(2) Install the steering wheel damper on the steer-
ing wheel. When damper is installed, it must be posi-
tioned on the steering wheel as shown in (Fig. 39).

the airbag, horn switch wire, and speed control
switches (Fig. 37). Attach the wire routing clip to the
studs on the airbag module.
(6) Install the airbag module in the steering wheel.
(7) Install the 3 bolts (1 in each spoke of the steer-
ing wheel) attaching the airbag module to the steer-
ing wheel. Tighten the 3 airbag module attaching
nuts to a torque of 11 N´m (100 in. lbs.).

GEAR
DESCRIPTION
This vehicle is equipped with a rack and pinion
power steering gear (Fig. 1). It is mounted to the
underside of the front suspension cradle/crossmem-
ber.
The steering column is attached to the gear
through the use of an intermediate shaft and cou-
plers. The outer ends of the power steering gear's
outer tie rods connect to the steering knuckles.
NOTE: The power steering gear should NOT be ser-
viced or adjusted unless DaimlerChrysler Corpora-
tion authorizes. If a malfunction or oil leak occurs,
the complete steering gear should be replaced.
Only the outer tie rods may be replaced separately
from the rest of the gear.
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 oil 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 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.
WARNING
WARNINGS AND CAUTIONS
WARNING: POWER STEERING FLUID, ENGINE
PARTS AND EXHAUST SYSTEM MAY BE
EXTREMELY HOT IF ENGINE HAS BEEN RUNNING.
DO NOT START ENGINE WITH ANY LOOSE OR DIS-
CONNECTED HOSES. DO NOT ALLOW HOSES TO
TOUCH HOT EXHAUST MANIFOLD OR CATALYST.
WARNING: FLUID LEVEL SHOULD BE CHECKED
WITH THE ENGINE OFF TO PREVENT PERSONAL
INJURY FROM MOVING PARTS.
CAUTION: When the system is open, cap all open
ends of the hoses, power steering pump fittings or
power steering gear ports to prevent entry of for-
eign material into the components.
REMOVAL
REMOVAL - LHD GEAR
(1) Remove cap from power steering fluid reser-
voir.
(2) Using a siphon pump, remove as much fluid as
possible from the power steering fluid reservoir.Use
care not to damage the filter mesh below the
fluid surface.
