Well, I rebuilt the track rod bushing, lower ball joint, new tie rods on both side. Did the rear subframe bushings. Took it to the indy alignment shop. Car still has horrible vibration > 50 mph. I don't think it was aligned properly. It seems to drive straight. What are other variables?

What to do next? Very frustrated at this point. I tried to get close as possible when counting the groves on the track rod and tie rod.

Thanks,

John

Tires??

The problem didn't worsen until front end rebuild.

I know it is hard to identify, but does it feeel like a bouncing vibration or left to right vibration? Do you feel it in the steering wheel or body of the car? Does the vibration differ in a turn? Does it change accelerating or hitting the brakes? Any or all of the different little nuances could help pinpoint it.

OK I will ask the silly question,After all this work did you look into the brake rotors,a warped rotor will cause vibration,or a brake caliper stuck,or a bent rim, or the tires with a bad belt as asked by surf-n-turf.
