325is driftshaft problams

alright. so this might sound dumb, but i cant figure out whats happening!! i replaced the clutch a few months ago and tightened everything down putting the drive shaft together. and anyways so now when i shift (not really slow and smooth, but not dumping or anything) and when i'm at slight throttle i get a thud / extra vibration noise. and when i replaced the clutch i also replaced the guibo and the center bearing. so December sometime i got under the car again and saw that the drive shaft was loose in the middle. so i tightened the coupler (if thats what you want to call it) and i did this again about a month ago. BUT i am still having the same problem....so anything thoughts ? so there a way to pull the drive shaft together more and then tighten or what ??

Check the Bolts that hold the driveshaft to the Diff... had that issue on my old 325...
