Vibration question '94 cavalier
I have a question about a vibration I feel between 70mph and just before 80mph. I feel it in the wheel a little, but over all the whole car gets it too. I replaced the tires a few months ago and watched them balance them, they are all with in specs. I replaced the rear shocks at that time. The front end does not seems loose to me and I am not sure what is causing this. Can someone point me in the right direction?
