im getting a vibration a 60mph and it doesint go away if i go faster i went up to 85 or 90 and it still does it. it happines when im coasting with the clutch in, if i put it under load it goes away. i tried turning the drive shaft i had it balanced and new u joints, wheel alinement and tire balanced, we put the car up and got the wheels spinning and the back right was moving a bit, so we put the front tires on the back and i took it for a drive and it still got the same vibration, havent got a chance to up it up and see if the wheels still moving. any ideas what it could be i thought it could be a bent axle, but wouldent that go away if i went faster the 60, like a unbalanced tire. thanks

Drive shaft Yoke might be done, I had to buy a new drivshaft to fix the problem, no matter how many u joints I tryed it still vibrated so i finally gave up and baught a new shaft.

they checked the drive shaft when they did the ujoints it was a really good place that just does drive shafts so i dont think it that, but thanks for the reply
