Just recently I installed a new-to-me rear diff (3.73 LSD) and full exhaust, and I've got a low speed clunking when getting on and off the accelerator, and when putting the clutch pedal in and out. If I pump the clutch in and out it's almost constant and feels like it's in the middle to rear of the car.
Background - car has new poly subframe bushings, poly TA bushings, new trans mounts, poly motor mounts, fresh Redline in the diff, new CSB, new guibo, new brake calipers and pads, new rotors, all new e-brake hardware.
At first, I thought it was the CAB's - they're getting replaced along with CA's and sway bar end links, inner and outer tie rods, but this sound is more from the rear, and more pronounced with the clutch engaging/disengaging. Slower speeds only it seems - at higher speeds either I can't notice it or it's not happening.
Possible issues - the halfshafts are leaking at the seals, on the ends that bolt to the diff, not the boots themselves. Not sure how to replace those, though I haven't really looked into it much, so it might be easy.
Diff mount looked just fine, but it might be causing the clunking - not sure how I'd diag that.
I'm fairly certain I did not thread the center locking collar from the front to rear driveshaft sections together - though I can't imagine that would cause the sound I'm getting.
Exhaust seems secure, and I used all factory stuff, and even shaking the heck out of it (car stopped, foot on tailpipes) it doesn't hit, so for now I'm ruling that out.
Ideas? Wed I'm going to drop the heat shield and inspect the csb - maybe I trashed it already, though the driveshaft u-joints were smooth as silk.
