Dear Doctor: I own a 2003 GMC Sierra 1500 pickup and now have a clunking sound in the steering column. A mechanic said the sound is where the column goes into the gearbox. There was a recall, but I never got notification. I understand that even some of the vehicles repaired under the recall still have the problem. Do you have the solution? Robert
Dear Robert: An ongoing problem on this model-year truck has been the lower steering shaft failure. GM had a grease repacking kit for a while and now an updated lower steering shaft. I have replaced a number of these steering shafts over the years. As for any recalls, check the dealer service department with your VIN number. I can say that your vehicle will feel like new once the shaft is replaced.
