OK, if you have read any of my previous recent threads you may know that my 1998 Ki00 GMC Suburban started making a low grinding noise when put into 4WD. The dealer worked on it and installed front Transfer case bearings and seal and the vehicle speed Sensor. A week later I had the rig towed home. The whole car died as I pulled out of a parking space. I , at the time noticed that the Theft deterrent system Chirpped about 5 times. Then...DEAD. When I tried to coast to the side of the road I noticed my steering wheel Just made a clicking noise as I turned it-it was not engaging the steering linkage. I asked here if this was part of the theft deterrent system and was told that it was not. Now after replacing the Ignition Lock Cylinder, I am not getting any anti-theft BS. Everything starts fine. The steering though is now giving me problems. When the car is OFF, The steering wheel can be turned; but it does not turn the tire- like it is not engaging in the steering box. I see the rubber covered shaft under the hood turn with the wheel; but the tires do not move! I called the service manager- he assured me that this cannot be related to service performed by them 2 weeks ago. When I asked what system was the likely culprit. He said "could be a bolt (100 dollar fix), could be something else One Thousand dollar fix)" Last night I saw on another forum something about a clock spring in the steering box could be the culprit also it could affect the SIR (Airbag). I am having a steady AIR BAG light. Any one know what kind of fix this is. A DIY- I am a pretty decent mechanic- just have never torn into a steering box before.
