After spending $450 at AutoServ for what 'they' diagnosed as the original problem I drove home and nothing changed. They replaced the right rear axel and bearings, etc. and full alignment. As soon as I left the repair shop when I drove home and reached about 50-52 mph the car starts to shake which tells me 'maybe' there's something wrong the driveshaft. Very frustrating. Sorry, just blowin' out steam.
