Wierd Noises

[BahnE30]

i'll try and describe this the best i can, here we go, coming out of right hand corners if i put my foot into it i get a wierd grinding noise, if the corner is bumpy what so ever i feel a slapping against the body at the back of the seats from the drive shaft area, i don't get the noise out of a left hand corner and the slapping seems slim to nil almost like something is lose on the pass side, tranny mounts look new and are tight, havent looked at the shaft but it'd be wierd only doing it when one side of the car is loaded up?
any ideas guys, i can give more details if necessary...

Check your CSB and diff mount/mounting hardware.

diff looks good, bolts are tight, i somehow thought it was going to be the CSB, fuck
