I really hesitate to say this, because I know I'll get flamed for it (as it isn't MB protocol)...but I'm going to anyway. I asked a friend who is a trained MB mechanic (but now has his own business)(the dealer closed here many years ago) about this once, because I needed to remove the driveshaft for a transmission job. It was for a 70's 4 cylinder, maybe a 220. If this is the huge nut that clamps the splines, we simply used an air chisel with a dull-ended fixture. Hammer gently around the nut and it screws right off. Reverse the procedure to tighten.
