Hey Scotty. My 2004 GMC Yukon won't stay on a straight line when on the road. I am constantly making small adustments withthe steering wheel.....does not favor one side or other and I just got new tires which did not fix the problem......I'm thinking tie rod?

any worn part can do that, such as a tie rod. And so can an out of alignment front end. Realize good front end shops give free estimates and you can't check alignment yourself

I love you Scotty! Helluva man you are!
