Well, did you find out what it was?

Well I took apart the rearend and I didn't see anything and I changed out the u-joints now I just have the vibration when I let off the gas at 60-75 mph. Next step is to change the front wheel bearings and maybe have the tires balanced.

why dont you take the wheel bearings out and look at them. make sure they're not worn out or pitted. if they look ok you probably dont need to replace them. when you say you feel this on "decel" does that mean while braking? or just coasting?

Just while I am coasting, I don't feel the vibration when I put on the gas

I do not think it is wheel bearings. They generally make noise when going around corners or making turns.

Balance the tires and check to see if the wheel bearings need to be tightened. Alot of times they need to be tightened, and not replaced.

How bad is the vibration? Is it violent or barely noticeable?

aabensonae

At around 60-75 mph the shaking is violent but at any other speeds it really isn't noticable.

Thanks for the help guys

If you don't feel the vibration in the steering wheel its NOT a front wheel bearing issue or balence issue. Wheel bearing are very easy to check. Jack the car up and see if there is any play in the wheel (it shouldn't have any play). Also another very simple check-- jack each wheel up and spin it - it should spin straight if you see any wobble you could have a bad tire (belt shift) or bent wheel. Wouldn't explain the accel only condition but its easy and free.. Best to rule out the easy basic stuff first
