This problem is a sparatic problem and isnt occuring all the time. Occasinaly while driving down the road the car will get a heavy vibration in it. This vibration whil grow in intensity and almost fell like theres a flat tire in the rear of the car. The rear tires are good, no broken belts or anything. I had a sneaking suspicion that it could be a prob with my rear pass brakes but dont know if that makes sense.

I would jack up a rear tire and get it in the air, ck it like you would for a loose bearing, if one side doesnt do it try the other ( grab the tire up and down try and wiggle it, also grab it from side to side and wiggle it) let me know.
