This subject may have been beat to death in other threads but I didn't see any resolution. I have a 2006 TB LS 4.2 l6. I have tried some of the tricks that have worked for other people to get rid of the issue. The only thing I didn't do is replace the bearing and or bearings (yet) in the steering column. This feeling and noise is like nails on a chalkboard to me. :suicide: I just want to get it all figured out! I just installed dual exhaust so I don't hear it as much as I feel it anymore. Suggestions? Thoughts? Comments? Questions?
