i have an 03 explorer and it will shake at 65 mph and up.bad enough that i wont drive past 65 because of it. i no for sure it has a blown shock in the rear but would that cause this?personally i don't think so......its not a roter either. thanks
No. What this sounds like is a problem with the transmission. If it won't drive past a certain speed it's not a suspension problem (including an unbalanced wheel).
