2002 buick regal: gran touring suspension..left front..steering

Resolved Question:

I have a 2002 buick regal with gran touring suspension and have had a rapid clunking noise in the left front part of car. It sounds like it is in the steering system to me. I have had different shops try to find the problem with no success. Any ideas?

Have you checked the steering intermediate shaft being worn? GM has several problems with these being faulty.

Reply to Dan's Post: The problem has been in the car since approx 25000 miles. Would wear occur this fast?

This bulletin is being revised to provide information for identifying '06-'08 Impala I-shafts that have been produced using the new production process. Regal, Impala, Monte Carlo, Intrigue and Grand Prix vehicles ONLY -- continue to grease the I-shaft. For Allure and LaCrosse, continue to replace the intermediate shaft as necessary.


Please discard Corporate Bulletin Number 01-02-32-001K (Section 02 -- Steering).


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 customer's 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.

DO THIS

DON'T DO THIS

If the vehicle is equipped with the new design I-shaft -- grease the intermediate shaft.

If the vehicle is equipped with the previous (old) design -- exercise/stroke the shaft to redistribute the existing grease.

DO NOT replace the intermediate shaft.

Vehicles Equipped with the Old-Designed (greased) I-Shafts

For vehicles equipped with the old designed I-shafts which are already greased, remove the I-shaft from the vehicle. Exercise/stroke the intermediate shaft to redistribute the existing grease on the shaft.

Vehicles Equipped with the New Designed (non-greased) I-Shafts

If the vehicle is equipped with a non-greased intermediate shaft, remove the intermediate steering shaft from the vehicle. Lubricate the shaft using the steering column shaft lubrication kit, P/N 26098237, using the following procedure:

  1. Remove the steering intermediate shaft from the vehicle. Refer to Intermediate Steering Shaft Replacement in the appropriate Service Manual.

    Important: Make sure the intermediate shaft is being pressed over the ears of the solid shaft.

  6. Use a hard surface to ease the collapse of the intermediate shaft. It is best to use a pumping action when collapsing the shaft. Collapse the shaft as far as possible.
  7. Remove the rubber stopper plug from the yoke end of the shaft.

  9. Inspect the intermediate shaft for a minimum of 5 mm (0.2 in) (a) of grease on the shaft splines.
  10. Repeat Steps 4-9 if less than 5 mm (0.2 in) of grease is on the shaft splines.

    Important: Before installing the intermediate shaft in the vehicle, make sure to stroke and extend the intermediate shaft at least 15 TIMES to completely lubricate the internal surface of the slip joint.

  11. Reinstall the intermediate shaft into the vehicle. Refer to Intermediate Steering Shaft Replacement in the appropriate Service Manual.
