I have a 2001 V6 Chevy Blazer. When driving down the road, if I turn my wheel to the left you hear a loud noise. It's not a grinding noise, its just loud noise, I guess kinda like if you run over the grooves alongside the road, it's just a loud noise like that. I need a alignment for my vehicle but I don't think that noise is coming from that. Any clue on what it could be?
