I cant figure it out....
From 60 to 78mph....... It doesn't exist anywhere else.
Rotors are a bit shaky when braking.....could be that.
Wheels balanced, rims brand new, new ball joints, new wheel bearings, WTF?

I am bringing it to my man, John Nouri because I know he will be able to fix my mysterious vibration.
Help me John!

 

if the rims are brand new, put the old ones on.

it is possible to get bad rims

 

Yes on the rotors.

With all due respect, new wheels do not mean that they are correct for your car. The new wheels may be good and round but not center correctly for the car which is very typical for aftermarket wheels.

Start by telling us what wheels you have please.

 

John Nouri is on the case.
I know he will handle business, as usual!!

Keep you posted....
