Im not sure how to discribe this or even if im in the right area. But it seems when im driving that something is shaking almost directly under my seat. Maybe up a bit. Now i knoe its not the bushings or control arm, Just fixed those last year. And its not when i go over a bump it just happens randomly. And all it is is it sounds like something shaking back and forthl. Any ideas?

 

Snow in your wheels? Shaking goes up with speed?

 

i would agree with this. more specifically rear wheels. generally the rule of thumb is if you feel the shaking on your bum then its the rear wheels to look at, if its in the steering wheel its the front wheels to look at.
