hey guys, i need help figuring out what this vibration is. its not loud, and its not to crazy. i guess you could say its a medium vibration.

at any speed above 45 mph you can really feel it. after you let off the gas thats when the vibration starts, but if the motor is under load the vibration is very very suttle. the faster you go the worse it gets. the car is pretty much un drivable at 65 70 mph. the whole car shakes at that speed. at first i thought it was a tire unbalance, i checked all the wieghts on the wheels and one wheel was missing weights. i got it balanced and the issue still exists. im thinking its more of a drive line issue. bent axle? rear end? tranny? motor mount? it seems to be coming from the back half of the car, but it could be coming from anywhere. i have no clue. if any one can shed some light on my situation that would be great. thanks for all the help guys.

this is a very common problem this past year and it started with me lol its your transmission tailshaft bushing and/or yoke on the driveshaft....its worn down and creates play in the yoke of the driveshaft...ive had the exact same problems you mentions and this did it

the bushing is in the tail shaft if you can take that part off yourself and then take it to a shop to get it pressed in...the yoke def can yourself when i did mine i installed an alunium driveshaft too
