[QUOTE="ac427cobra, post: 9775509, member: 6247"] Well unfortunately the entire Terminator driveline can accumulate quite a large amount of backlash. It starts in the T-56, plus the output spline for the driveshaft, two u-joints, then add the differential innards (including the ring, pinion and side/spider gears, which in many cases is a lot) then the halfshaft splines, TWO CV joints on EACH of the halfshafts, and the knuckle/hub spline. Just with a normal car with say 60k or 70k miles on it will add up to quite a noisy chain of events. Even with 9/16" bolts and new diff mounts. The differentials can be corrected by replacing the posi unit and resetting the ring gear backlash. But a VAST majority of "Cobra Clunking" is from worn out OEM differential mounts (that really weren't any good even when they were new) and movement in the front 12mm undersized factory installed front subframe bolts. FWIW :thumbsup::coolman::beer: [/QUOTE]
