Please discard Corporate Bulletin Number 06-02-32-007E (Section 02 – Steering). Condition 1 Some customers may comment on a clunk noise heard and felt in the steering wheel while driving at slow speeds and turning. The clunk noise may appear to be directly in front of the driver. Hitting a bump while turning can produce the clunk noise. Sometimes the noise may be duplicated when the vehicle is sitting still and the steering wheel is turned 90 degrees in either direction before initially centering the steering wheel. Cause 1 The clunk noise may be caused by a slip/stick condition between the inner and outer components of the intermediate shaft. Important Revised design intermediate shafts went into production in the 2009 model year and are the only design currently available through GMSPO since approximately September 2008.
