weird hard thumping sounds from rear???

so in any gear as the hard i accelerate the hard the thump like if my car was slamming into something at first i wondered if it was my suspension but not i think it has to do with my differentials, idk im really worried about my drive shaft falling off or w/e lol S.O.S.

Yeah, pretty common. I temporarily alleviated the problem on one of my 7's in the past by wedging some thick rubber sheet material between the differential and body. Not a fix by any means, but worked until I could fix it.

depends, any diff. mount will last forever if you add pinion snubber above the nose of the diff.

Who makes pinion snubbers for FCs? haven't really seen any snubs in use with the stock diff, really only rotary drag cars but they run with a Ford 9"
