Ken, not being snippy here
It'* very hard to diagnose a problem from 2000 miles away. If you fixed the mount and joint, we need a fresh rundown on the problem.
There are any number of things that can cause that kind of problem. If you think it'* a wheel or tire, rotate the fronts to the rear and see if the problem is there still, or if it changes. While you have them off, inspect the brakes. With the fronts both removed, and the car on stands, put the trans in N (not running
) and spin the rotors. Any rotor/pad clash? Shake the hubs, and inspect all the underpinnings.
Is this still only happening at a particular speed, or is it under accelleration?
