I have a 2003 Tahoe, it has been leveled and had nearly every steering/suspension component replaced over time. I've been having a steering problem since I bought the truck that hasn't gone away through various alignments from different shops. The truck drives fine in a straight line, but the steering feels really sensitive to turning it will almost pull into turns once you start making them, but the most annoying issue I am having is that the steering won't center itself on left hand turns, it centers pretty good when you make right hand turns. If you make a left turn it will just continue going in that direction until you center it yourself. Any suggestions for what might be going on here?
