When I'm on the freeway going about 60 I feel a vibration when I left off the gas I get back on the gas and it goes away and I think its comming from the rear any suggestions?

you may need new tires, or you may need new sparkplugs and wires, that can cause bucking while acclerating, and has for me before, even though it might feel like the rear it could very well be the sparkplugs and or wires.

Could be the u-joints in the driveshaft.

It's is your driveshaft, it's loose. I am 100% positive.
