I have that world re-known Bonneville highway shake. it does shake at all under 50... but at 50 it gets violent.
I had new tires installed and balanced
new tie rods and wheel hubs
Full front computer alighment done.
But i still cant go on the highway with the car... could my axle be bent or something like that
thanks

Re: Teeth-rattling shaking at 50 mph ?
Something is definitely wrong and not the normal issue. The normal "Bonneville shimmy" is a vibration that is annoying but definitely not violent or something that would keep you off the highway. I would look at ball joints, control arm bushings, axles, shocks and struts, look for bent wheels, and really give a good look at the rear lateral links.

tire shop can check wheel when balancing the tire..
Look at control arm bushings upper and lower, ball joints and Tie rod ends as listed above.. my guess would be bushings. I would think a wheel hub bearing would make noise but have them checked as well. Also have the tire shop check the tires to make sure they are not out of round and that the wheels where installed and TQed in the correct order, could be a bad mounting job of the wheel or a defective tire..
