Rear end knocking under Acceleration and upon Deceleration

Check the top of the Subframe cage that goes over the Rear end for cracks. It should not be missaligned and i have never herd about any differential swaps causeing the issue of not ligning up.
To fix your Problem you can take a hole saw and drill into the subframe where the bolt and cage are located.(this is what i did on both sides).
It wont take you too long to do but you will need to weld the hole you cut out back in (I used a washer i bought at ace hardware) after you put in your new nut . I removed the cage inside and made my own design.
basically a piece of flat 1 inch steel with a Bolt welded on to one end so it had a lever or pivit point to press agains if i tightened or loosened them.
it sounds like something else is wrong. Check the Subframe next to the tank there are 4 mounting bolts you could have broken one of them and it twisted the Subframe.
