I think I know the exact sound and I have come to the conclusion that it must be the intermediate steering shaft, based on where the sound comes from and the overall reliability of the rest of the vehicle. Check out this link... there are updated parts to fix this. Looks like about $95 from GM Parts Direct, 1 hr of your time and 2 bolts.
I need help!! When I turn my truck to the left to make a full turn it squeals like a pig. It sounds like its coming from the area of the left wheel. I think it's only when the truck is cold. Any ideas??
My truck is a 2006 2500hd silverado. When the truck is cold (been sitting for a few hours) and I make a left turn onto a street, it squeals. The sound is either quiet or loud. Sounds like a pig is under my wheel. I took the tire off and sprayed silicon spray on the all rubber parts. Helped a little but noise is still there. Any ideas?? I have a new 1 year old steering pump and fluid is full
