Power Steering System Squeaking Noise Repair Procedure AFFECTED VEHICLE RANGE CONDITION SUMMARY: POWER STEERING SYSTEM SQUEAKING NOISE Situation: On some S-Type, X-Type and XJ Range vehicles within the VIN ranges above, a squeaking noise may be apparent from the power assisted steering system when the steering wheel is rotated in either direction. The noise is caused by a seal inside the steering rack. The noise can be transmitted through the steering column and steering wheel, making it difficult to diagnose. This bulletin does not address any other PAS noises, such as pump or drive belt related noises. Action: In the case of a verified customer complaint matching the description above, refer to the Repair Procedure detailed in this bulletin and complete the service fix.REPAIR PROCEDURE PAS SQUEAK/FLUID ADDITIVE Open driver’s door. Ensure the gear lever is in either neutral or park, the parking brake is ‘ON’, and the ignition is ‘OFF’. Open hood and install fender protectors. 4. Remove the power steering fluid reservoir cap (and filter mesh on XJ and S-Type vehicles) and ensure the fluid level is correct. (Figure 1) 5. Using a suitable clean syringe, remove 50 ml of steering fluid. NOTE: The fluid additive must only be added once and the supplied label must then be affixed to the power steering fluid reservoir. 6. Replenish the power steering fluid reservoir with 50 ml of the specified fluid additive (C2S 48887). 7. Affix the supplied label to the power steering fluid reservoir NOTE: Suitable temperature reading equipment must be positioned into the power steering fluid reservoir, (filter mesh must be removed on XJ and S-Type vehicles) and that the temperature can be read while carrying out the heating process. 8. Insert the temperature reading equipment probe into the power steering fluid reservoir (about halfway into the depth of the fluid). HEATING THE STEERING FLUID TO 100°C +/- 5°C (212°F +/- 10°F) 1. Turn ignition ‘ON’ and start the engine. With the engine idling, turn the steering wheel from lock to lock four times to cycle the fluid additive into the system. (Figure 2) CAUTION: Under no circumstances hold the steering wheel on full lock while heating the steering fluid (to avoid damage to the steering system). CAUTION: While carrying out the following procedure, ensure that 105°C (221°F) is not exceeded. 3. While stationary and with the steering wheel in the center position (road wheels in the straight ahead position), turn the steering wheel 90° (quarter turn) right and hold firmly with both hands. (Figure 3) ^ Increase the engine speed to 3000 rpm. ^ Monitor the power steering fluid temperature until 100 +/- 5°C (212°F +/- 10°F) is reached. PERFORMING THE STEERING MANEUVER NOTE: The steering maneuver should be carried out on a hard flat surface outside of the workshop. CAUTION: Do not hold the steering wheel on full lock for more than two seconds as this may cause damage to the steering system. 1. Verify the power steering fluid temperature is at 100 +/- 5°C (212°F +/- 10°F), engine idle speed set between minimum 900 rpm and maximum 1000 rpm. 2. Turn the steering wheel to full lock and hold for two seconds.

Subject: Clunk Felt/Noise Heard From Steering Column Steering Gear and/or Front Of Vehicle During Turning Maneuver and/or Steering Wheel Rotation (Replace Intermediate Shaft As Directed) Models: 2001-2004 Buick Regal 2005-2007 Buick Allure (Canada Only), LaCrosse 2000-2008 Chevrolet Impala 2000-2007 Chevrolet Monte Carlo 1998-2002 Oldsmobile Intrigue 2004-2007 Pontiac Grand Prix Condition Some customers may comment on a clunk type noise coming from the front of the vehicle while driving during a turning maneuver. This condition may also be felt through the steering wheel when the vehicle is stationary and the wheel is rotated from steering stop to steering stop. Some vehicles may only exhibit the noise once for every 360°of wheel rotation. On all other vehicles this clunk noise will be noticed during low speed acceleration or deceleration typically in light turns of the steering wheel or when applying/releasing the brakes. Cause This condition may be caused by a “slip stick” condition resulting in the clunk noise or feel through the steering wheel. Diagnostic Tip Important: This condition is commonly misdiagnosed as originating in the steering gear and has resulted in the replacement of numerous steering gears without correcting the concern. Attempt to duplicate the customers concern and isolate the I-shaft by following the procedure below: 1. Locate a large area (parking lot) where the vehicle can be turned in a tight circle. 2. Turn the steering wheel to the right and/or left all the way to the steering lock then off the steering lock a 1/4 turn. 3. Drive the vehicle approximately 5 km/h (3 mph) in a circle preferably over rough pavement or seams on the road surface. 4. If a clunk is felt in the steering wheel the MOST likely cause is the I-shaft – not the steering gear. Continue with the correction. 5. Drive the vehicle straight ahead at idle speed while applying and releasing the brake pedal. Listen/feel the steering wheel for the clunk-/noise condition. Correction
