My MS has a vibration around 60 MPH. Tires have been balanced twice so that's not the problem. Alignment was done not too long ago, so i don't think that is the problem. There doesn't seem to be any looseness in the wheel bearings at rest, so that doesn't seem to be the problem. Any suggestions as to what the problem could be? It only started to occur recently, but it is very consistent.

 

Do you have custom wheels on the car?

 

Brake rotors possibly?

 

Does it shake when your braking or just cruising?

 

Tires could be cupped too

 

Sounds like a bent wheel to me. Or like Sebba said, the rotors.

 

They should have seen if it was bent when they balance the tires.

 

They may have seen it and not mentioned it... by maybe assuming you already knew. Its happened to a good amount of people I know. Mostly by Sears and WTC.
