My s-10 vibrates going down the road when I let off the gas it stops. It doesn't do it when in park.I have changed one motor mount other one is okay, I changed transmission mount, changed center bearing on drive shaft.I can't figure what could be the problem. Could it be the transmission causing this. Please help.I put new tires on back front tires are fine

Is the vibration in the body or the steering wheel? If body only check tyres and rims and uni's first.

Its in the body and I had new tires speed bal. When put on, I did a visual inspect. On front tires, I had uni's visually inspected and was told they was good, is there a machine I could have it put on to pin point it without doing more guesswork

Were the u joints removed to inspect them?Not sure you could tell otherwise. That in itself is'nt costly, its knowing how to install them w/o damaging them.
Is the vibration more towards the front or the back?
A machine?Lol>
