If your car or truck is shaking, especially when you go over 50 MPH, don't panic.  The fix could be simple and cheap.  Given all of the crazy weather we've been having recently (super crazy cold, ice rain, blizzards), there's a good chance you might have snow and ice in your wheels.

As the snow and ice gets caked into only one part of the rim, it makes the wheel unbalance.  This is why they wobble at higher speeds.

If you can't pull your vehicle into a heated garage, SOME dealerships and mechanics will clean out your wheels at no charge.
