I have a 2002 Chrysler T&C. It has a rattle in the front suspension especially on a rough or bumpy road, it can also be heard sitting still and turning the steering wheel back and forth. You can also feel the rattle in the steering wheel a little. Also there is a shutter in the steering wheel when you turn sharply (like in a parking lot)!

 

the poping I have seen swaybar links and bushings cause that


This is for the shudder



THIS BULLETIN SUPERSEDES SERVICE BULLETIN 19-004-03, DATED AUGUST 29,
2003, WHICH SHOULD BE REMOVED FROM YOUR FILES. THIS IS A COMPLETE
REVISION AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS.
SUBJECT:
Steering Shudder
OVERVIEW:
This bulletin involves replacing one of the two power steering cooler hoses with a new
longer power steering hose and if necessary, installing a fin packed power steering cooler.
MODELS:
2001 - 2005 (RS) Town & Country, Caravan, Voyager
2001 - 2005 (RG) Chrysler Voyager (International Markets)
NOTE: This bulletin applies to right hand and left hand drive vehicles equipped with
a 3.3L or 3.8L engine (sales code EGA, EGM, EGH) built on or before
December 8, 2004 (MDH 1208XX)
SYMPTOM/CONDITION:
A shudder (vibration) is felt inside the vehicle while turning the steering wheel at idle or
during low speeds such as a parking lot maneuver. The shudder may be felt in the steering
wheel, seat, and/or body.
DIAGNOSIS:
1. Verify the condition: - Perform stationary turns and/or low speed turns in drive and
reverse. Perform the evaluation with the A/C in the on and off position. Is steering
shudder detected?
a. Yes >> Go to Step #2.
b. No >> Further diagnosis is needed, this bulletin does not apply.
2. Inspect for the presence of a power steering finned cooler. Is a finned cooler
present?
a. Yes >> Go to ā€œReplace Power Steering Hose - Step #1ā€.

INSTALL FINNED COOLER:
CAUTION: Throughout the following procedure, special care should be taken to
prevent introducing contamination into the power steering system.
1. Open the hood.
2. Remove the cap from the power steering fluid reservoir.
3. Using a siphon pump/suction gun, remove as much power steering fluid as possible
from the power steering fluid reservoir.
4. Remove and save the constant tension spring clamp securing the power steering
return line hose to the power steering fluid reservoir.
5. Remove the rubber hose portion of the power steering return line from the power
steering fluid reservoir fitting.
6. Drain the power steering fluid reservoir into an appropriate container.
NOTE: This fluid should not be reused to avoid introducing contamination from the
container.
7. Raise the vehicle on an appropriate hoist.
8. Remove the fuel vapor canister.
9. Locate the bracket connecting the power steering return line cooler loop to the cradle
reinforcement plate (Fig. 1).

10. Remove the fasteners connecting the cooler line to the reinforcement plate. Save the
fasteners for use in Step #17.
11. Locate the bracket connecting the power steering pressure line to the cradle
reinforcement plate (Fig. 1).
12. Remove the fastener connecting the bracket to the reinforcement plate. Save the
fastener for use in Step #18.
13. Remove and discard the J/U nut clip on the bracket.
14. Locate and unscrew the tube nut connecting the power steering return line to the
steering gear pinion housing.
NOTE: The tube nut will remain loosely assembled to the power steering return line.
15. Drain the remaining fluid into an appropriate container and discard the loop cooler line
that was removed from the vehicle.
NOTE: This fluid should not be reused to avoid introducing contamination from the
container.
16. Install the new power steering return line, p/n 04743473AE. Attach the power steering
return line tube nut to the steering gear pinion housing and tighten to 27.1 - 35.0 NĀ·m
(240 - 310 in. lbs.).
17. Reuse the fastener removed in Step #10. Install the fastener into the left weld nut on
the cooler fin pack bracket and the left hole in the cradle reinforcement plate. Tighten
the fastener to 9 - 11.3 NĀ·m (80-100 in. lbs.) (Fig. 2).

18. Line up the pressure line bracket and the right weld nut in the cooler fin pack bracket.
Reuse the fastener removed in Step #12. Install the fastener through the right hole in
the cradle reinforcement plate, the fin pack bracket and the pressure line bracket.
Tighten the fastener to 9 - 11.3 NĀ·m (80-100 in. lbs.) (Fig. 2).
19. Install the fuel vapor canister.
20. Lower the vehicle.
21. Install the constant tension spring clamp removed in Step #4 onto the rubber hose on
the power steering return line. Slide the clamp so that it is 3 inches from the end of the
rubber hose.
22. Push the end of the rubber hose portion of the power steering return line onto the
power steering fluid reservoir suction port. Secure the hose by sliding the constant
spring tension clamp installed on the hose in the last step, to within 6 mm (0.25 in.) of
the end of the rubber hose. Be sure the hose clamp is installed past the bead on
fluid reservoir fitting.
23. Check the vehicle production date. Was the vehicle built on or before September
13, 2004 (MDH 091344XX)?
a. Yes >> Go to ā€œReplace Power Steering Hose - Step #1ā€.
b. No >> Go to ā€œSteering/Pump - Standard Procedure - Step #1ā€.

REPLACE POWER STEERING HOSE:
1. Cut 850 mm (33.5 in.) of power steering hose (p/n 05135964AA) or equivalent.
2. Cut 790 mm (31 in.) of 15.9mm (5/8 in.) or 17.5 mm (11/16 in.) convolute tubing. Place
the convolute tubing around the power steering hose.
3. Open hood and remove the power steering reservoir cap.
4. Raise the vehicle on an appropriate hoist.
5. Locate the power steering cooler attached to the crossmember support. Remove the
forward (closest to front of vehicle) hose from the cooler and tube. Drain the power
steering fluid in an appropriate container.

STEERING/PUMP - STANDARD PROCEDURE
WARNING:FLUID LEVEL SHOULD BE CHECKED AND ADJUSTED WITH ENGINE
OFF TO PREVENT INJURY FROM MOVING ENGINE COMPONENTS.
CAUTION: Use only MoparĀ® ATF+4 Automatic Transmission Fluid (MS-9602) in
power steering system. Use of other MoparĀ® power steering fluids
(MS5931 and MS9933) should be avoided to ensure peak performance of
the power steering system under all operating conditions. Do not overfill.
Read the fluid level through the side of the power steering fluid reservoir. The fluid level
should be within ā€œFILL RANGEā€ when the fluid is at a temperature of approximately 21Ā°C
to 27Ā°C (70Ā°F to 80Ā°F).
1. Wipe the filler cap and area clean, then remove the cap.
2. Fill the fluid reservoir to the proper level and let the fluid settle for at least two (2)
minutes.
3. Start the engine and let run for a few seconds, then turn the engine off.
4. Add fluid if necessary. Repeat the above steps until the fluid level remains constant
after running the engine.
5. Raise the front wheels off the ground.
6. Start the engine.
7. Slowly turn the steering wheel right and left, lightly contacting the wheel stops.
8. Add fluid if necessary.
9. Lower the vehicle, then turn the steering wheel slowly from lock-to-lock.
10. Stop the engine. Check the fluid level and refill as required.
11. If the fluid is extremely foamy, allow the vehicle to stabilize a few minutes, then repeat
