High speed vibration
 

Hello everyone, i have an 88 gxl and when I jump on the freeway and hit approx 75mph and higher the steering wheel starts to shake. It seems as if the whole car is shaking. I just had the front wheels balanced and that only helped a little bit. Any help on how to fix this would be greatly appreciated. thanks in advance----ren

Did you check the air in the tires?

air in tires checked out ok.

Have you had front alignment lately? Tie Rods could be worn or damaged.

Bad tire tread? Did you have the rears balanced, too?

Could it be the tailshaft out of balance?

Check the insides of your wheels for bends...
