I've had this issue for a while now and I'm really getting tired of it, especially now with the front end being out of alignment. There is a good 2-3 inches difference between the left side and the right side of the front vehicle height. (the passenger side is the lower side) I know that I'm going to have (and will) replace the front shocks with the Bilstien HD's. Does this sag of one side mean that I will need to replace the springs as well, or are they still good? Currently sitting at 160,000 miles with original OEM front suspension. I'm planning on taking the Envoy to a local shop that was recommended to me and see what they say about it. I just wanted to get everyone's thoughts here first!
