A friend of mine has a 92 Camaro that he has been battling a high speed wobble with for over a year now. It starts at about 65 mph and by 80 the whole car is shaking. I've taken a look at the car briefly when I could, and didn't notice anything too extremely out of the ordinary. It is dog tracking a bit with the rear shifted about 1" off center towards the drivers side.

He has replaced the driveshaft, center link, inner and outer tie rods and adjustment sleeves, idler arm, lower ball joints, front sway bar bushings, inner and outer front wheel bearings, calipers and rotor, wheels and tires.

That's a pretty exhausting list of replacements, you would think he'd have solved it by now. Any ideas of where to look next?

 

Have you taken it to an alignment shop after all those changes? Are you sure the subframe isn't bent somewhere?

 

Oh yes. I didn't mention it above, but it has been aligned MANY times. Along with having the tires rebalanced about as many times. The subframe looks okay.
