vibration problems

[camaro keith]

Hey guys i just replaced my rack and pinion in my car and had it aligned and now when i hit 55mph or higher i have a nasty vibration any ideas what it could be? thanks keith

are you sure you bolted everything down tight? did you rotate tires? maybe a tire has a broken belt

i am pulling my tires off tomorrow and i am going to have them rebalanced see if that is the problem and i am sure everything was tightened down.

Switch the front tires to the rear and see if that vibration now is in the rear.
