I have a 2006 Chevy Silverado and I have a ratling noise in the steering column. It only has 13,000 miles on it.You do not have to hit a bump to get it to rattle. It has not been wrecked. What could this be?
There is a TSB on this that refers to the steering shaft as the cause of the problem. There is a new design that needs to be installed and should be covered under your warranty.
