Shaking on highway

[Little6pack]

Ok here is the issue. When I get up to 60-65 the car starts shaking. My turbo hood looks like it is vibrate off!

Ok Here is what has been done.

New front tires with balance, Old rear tires with balance.
I noticed I had the rears PUMPED up to 50 for the winter storage.
Let air out to 32.

Car still shakes?

Any ideas what to look for??

I have heard a twisted belt in tire could do this?

Do you feel it more from the steering wheel or from the floor/seat area? It sounds like a tire issue; maybe a bad belt in the any of the tire(s), could be a flat spot in the rear from storage, could even be a bent rim. Occasionally repositioning the tire on the wheel (breaking it down, rotating the tire and re-seating) will work.

Did it do it prior to sitting all winter?

 

[novaderrik]

jack the car up and spin each wheel and see if any of the wheels are out of round or if a rim is bent.
or maybe a wheel balance weight fell off.

Since when did your son's Monte turn into your Limited?
Switch your rears with his. He my have got a flat spot on the tires from sitting even though you pumped up the tires. Even if it doesn't fix it he'll probably steal your wider tires anyway.

Happened to me once. Flat spot on the tire. Next time you do winter storage put some bullsh-- tires on and let it sit or put the car up on jack stands.
