when im at a stop if i give the car heavy pedal but not flooring it.. it will make a very slight jerk/clunk feel from the rear-end its not audiable nor effects driveability but i can feel it
ive heard that a slight jerk/clunk is normal

had u-joints inspected and are in good condition trans-mount is also new
diffrential fluid level is full

could it be a DIFFRENTIAL problem occuring or is it just normal operation
cuz at normal pedaling it doesnt do it
help!

 

i would begin by looking at all your rear bushings in the suspension, the control arm bushings, panhard bar bushings and sway bar bushings. it is possible there is wear in your rear end and that can cause some noise and such under heavy loads, but its a good idea to start with the cheaper and easier stuff just to eliminate them if the bushings arent the problem.

 

How 'new' is the trans mount?

They dont last very long if you drive hard!
