Differential rocking when accelerating and stopping

Okay i posted on the M3 forum about how my rear end is making noises, and it turns out that my differential is rocking back and forth during stopping and accelerating. Im posting it here because the principals are the same and i believe e46 could have the same problems therefore, I'm wondering what could be the reason for this movement and also what parts should be bought in order to fix it. I was thinking bad differential bushings could cause it but however i don't really know much about inspecting differentials.

Better do the subframe-to-chassis floor bushings as well, and don't forget to inspect for cracks in the chassis floor and reinforce the area with the subfloor plates and/or structural foam. Watch out dumping that clutch between shifts, that's what causes the damage. It's almost like the car punishes those whom drive like douchebags.
