Has anyone else noticed this? I own a 2007 LS Trailblazer that has 73000 miles on it. At about 45000 miles I started noticing a pinch or mild vibration when turning in the steering column that I have yet to identify. The funny thing is that prior to purchasing this TB, I test drove a used one on the lot that was a 2005 and had 45000 miles on it and I distinctly remember this same pinch feeling while turning in the steering column on that one. That was one of the reason's I wound up buying new. New tires were purchased at 58000 miles. pinch feeling is always there and just had it to the dealer for an oil change and "safety inspection" with no issues whatsoever noticed.
