Help how does diff and drive shaft separate

I'm trying to take out my differential right now, and I'm stuck with the drive shaft stuck on the differential. how do i separate the two? i took off the 6 e12 torx bolts, and i tried to separate the differential from the drive shaft but it won't budge, i manages to slip off a cap, but it seems like there is grease and ball bearings in there? do i try to separate that?

no! put the cap back on and check for two groves on the driveshaft flange where it slips into the pumpkin flange. take a big screw driver or so and push it out a little, turn 180degrees, push out there... turn again... and so on.

edit: or are you talking about a e46? the driveshaft flange of the e46 doesnt have these groves :-(
it is a little harder to get it out the. take a piece of wood an gently hammer on the shaftflange while turning it... takes some time sometimes...

yeh i just saw pictures if the drive shaft and differential separated

did i mess up the dive shaft bearings?

going to try to hammer it off tomorrow with some grease, saw the grooves you were talking about. seems like the drive shaft is kinda on tight. needs some amount of force

and yeh for a e93 m3

Screwdriver in those two slots where the driveshaft meets the cupped pinion flange. Twist or pry it out using those two slots. You will likely need to undo the bolts holding the center support bearing to get it free of the pinion flange.
