2005 CHRYSLER CARAVAN lock

CONDITION POSSIBLE CAUSES CORRECTION
SUCKING AIR SOUND 1. Loose clamp on power steering
fluid return hose.1. Tighten or replace hose clamp.
2. Missing O-Ring on power steering
hose connection.2. Inspect connection and replace
O-Ring as required.
3. Low power steering fluid level. 3. Fill power steering fluid reservoir to
proper level and check for leaks.
4. Loose clamp on fluid supply hose. 4. Tighten or replace hose clamp.
SQUEAK OR RUBBING
SOUND1. Steering column shroud rubbing. 1. Realign shrouds as necessary.
2. Steering column shaft rubbing. 2. Move or realign item rubbing shaft.
3. Clockspring noisy. 3. Remove clockspring. Reinstall wheel.
If noise is gone, replace clockspring.
4. Seal lubrication inadequate. 4. Lube seal (if external).
5. Steering gear internally noisy. 5. Replace steering gear (if no other
cause can be found).
SCRUBBING OR
KNOCKING NOISE.1. Incorrect tire or wheel size. 1. Replace incorrect size tire or wheel
with size used as original equipment.
2. Interference between steering
gear and other vehicle components.2. Check for bent or misaligned
components and correct as necessary.
3. Steering gear internal stops worn
excessively allowing tires to be
steered excessively far.3. Replace steering gear.
* NOTE: There is some noise in all power steering
systems. One of the most common is a hissing
sound evident when turning the steering wheel
when at a standstill or when parking and the steer-
ing wheel is at the end of its travel. Hiss is a very
high frequency noise similar to that experienced
while slowly closing a water tap. The noise is
present in every valve and results when high veloc-
ity fluid passes valve orifice edges. There is no
relationship between this noise and the perfor-
mance of the steering system.** NOTE: A light clunk may be felt or heard during
steering wheel reversal while vehicle is stationary.
This results from internal steering gear rack move-
ment at the bushings and in no way affects the per-
formance of the steering system. This movement
may be felt in the steering components during
steering wheel reversal.
*** NOTE: Power steering pump growl/moan/groan
results from the development of high pressure fluid
flow. Normally this noise level should not be high
enough to be objectionable.

EXCESSIVE STEERING
WHEEL KICKBACK OR
TOO MUCH STEERING
WHEEL FREE PLAY.1. Air in the fluid of the power
steering system.1. Bleed air from system following the the
power steering pump initial operation
service procedure.*
2. Power steering gear loose on
cradle/crossmember.2. Inspect power steering gear mounting
bolts. Replace as necessary. Tighten to the
specified torque.
3. Steering column coupling or
intermediate shaft worn, broken or
loose.3. Replace steering column coupling or
intermediate shaft.
4. Free play in steering column. 4. Check all components of the steering
column and repair or replace as required.
5. Worn lower control arm ball joints. 5. Replace lower control arm ball joints as
required.
6. Loose steering knuckle-to-ball joint
stud pinch bolt.6. Inspect pinch bolt, replace as necessary,
and tighten to specified torque.
7. Front wheel bearing loose or
worn.7. Replace hub and bearing as necessary.
8. Loose outer tie rod end. 8. Replace outer tie rod end that has
excessive free play.
9. Loose inner tie rod. 9. Replace power steering gear.
10. Defective steering gear rotary
valve.10. Replace power steering gear.
* NOTE: Steering shudder can be expected in new
vehicles and vehicles with recent steering system
repairs. Shudder should dissipate after the vehicle
has been driven several weeks.
** NOTE: To evaluate this condition, it may be nec-
essary to disconnect the coupling at the base of the
steering column. Turn the steering wheel and feel or
listen for internal rubbing in steering column. To
avoid damaging the column clockspring, note the
following. Before disconnecting coupling, place
tires in the straight-ahead position and center steer-
ing wheel. Once disconnected, DO NOT rotatesteering wheel more than one revolution in either
direction and place steering wheel in original loca-
tion before reconnecting coupling. If this position is
lost, the steering column clockspring must be
recentered following the procedure found within the
procedure for steering column installation in the
steering column section.
*** NOTE: Increased low speed or stationary steer-
ing effort can be expected if the steering fluid is at
a high temperature. High fluid temperature usually
results from high engine rpm due to trailer towing,
ascending grades, or racing the engine for pro-
longed periods of time.

WARNING
WARNINGS AND CAUTIONS
(Refer to 8 - ELECTRICAL/RESTRAINTS - WARN-
ING)
WARNING: BEFORE BEGINNING ANY SERVICE
PROCEDURES THAT INVOLVES REMOVING THE
AIR BAG. REMOVE AND ISOLATE THE NEGATIVE
(-) BATTERY CABLE (GROUND) FROM THE VEHI-
CLE BATTERY. THIS IS THE ONLY SURE WAY TO
DISABLE THE AIR BAG SYSTEM. FAILURE TO DO
THIS COULD RESULT IN ACCIDENTAL AIR BAG
DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

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.
DIAGNOSIS AND TESTING - STEERING
COLUMN
For diagnosis of conditions relating to the steering
column, (Refer to 19 - STEERING - DIAGNOSIS
AND TESTING).
REMOVAL
NOTE: Before proceeding, (Refer to 19 - STEERING/
COLUMN - WARNING)(Refer to 8 - ELECTRICAL/RE-
STRAINTS/DRIVER AIRBAG - REMOVAL).
(1) Make sure the front wheels of the vehicle are
in the STRAIGHT AHEAD position before beginning
the column removal procedure.
(2) Disconnect and isolate the negative (ground)
cable from the battery. Wait at least two minutes for
the airbag system reserve capacitor to discharge
before beginning any steering column, instrument
panel, or airbag system/component service.WARNING: WHEN AN UNDEPLOYED AIRBAG IS TO
BE REMOVED FROM THE VEHICLE, FIRST DISCON-
NECT AND ISOLATE THE BATTERY NEGATIVE
(GROUND) CABLE. ALLOW THE AIRBAG SYSTEM
RESERVE CAPACITOR TO DISCHARGE FOR TWO
MINUTES BEFORE BEGINNING ANY AIRBAG SYS-
TEM OR COMPONENT SERVICE. PERSONAL
INJURY MAY RESULT IF THIS PROCEDURE IS NOT
FOLLOWED.
(3) Remove the driver airbag mounting screws
(Fig. 2).
(4) Lift the airbag from its mount and disconnect
two airbag squib, speed control and horn connectors
(Fig. 3). Remove driver airbag. Properly store the
driver airbag out of the way. (Refer to 8 - ELECTRI-
CAL/RESTRAINTS - WARNING)
(5) Remove the steering wheel retaining bolt (Fig.
4).
(6) Remove damper (Fig. 4).
(7) If equipped, disconnect the remote audio con-
trol switch wiring from the clockspring (Fig. 4).
CAUTION: Do not bump or hammer on steering col-
umn or steering column shaft when removing steer-
ing wheel from steering column shaft.
CAUTION: When installing steering wheel puller
bolts in steering wheel, do not thread bolt into
steering wheel more than a half inch. If the bolts
are threaded into the steering wheel more than a
half inch they will contact and damage the clock-
spring.
