at speeds around 30-45mph if i let off the gas i can feel and hear a little bit of "slop" in the drivetrain, sounds like a clunk but not real loud. you can feel it more then anything else. i dont think it is the tranny mount but it is cracked a little so it might be that, i guess thats the first thing i should replace. but if it is not that, what else might it be? at faster speeds like 55-60 it doesnt make the clunk as loud, if at all. very hard to notice if its there or not. but the slower your going the more apparent it is. if i let go of the gas really fast it is stronger, but even if you let go of the gas extrememly slow you can still feel it a little, just not as strong.

 

check you u joints on the drive shaft.

 

ok i will check those. but if it was the ujoints wouldnt i probably have a vibration problem? the car is smooth as silk even up to 100mph.
