Re: jeep death shake
How many miles on the ride? I replaced the front diff. isolator bushings at ~75K on mine. Top one was pretty bad and the others not so much. Much higher miles may toast them all. Also, what are the conditions of the front struts and ball joints? A good alignment shop should catch all these items. All my stuff is new and I know it's good for at least 130 mph, and smooth as glass all the way up.
