W110 Pinion Seal Replacement

I've got all the parts together (including the special 36 mm socket) to replace the leaking pinion seal on the rear-end of my W110, and plan to do so some time this weekend.

From what I have heard, the W108 has a similar drive shaft/rear-end setup ad the W110/111. Is there anything I should look out for, from others who have done this job? I have heard recommendations to, in the re-assembly state, replicate the pinion nut's original position by marking it and counting number of turns to prevent mis-shaping the bearing crush sleeve.

I will also be replacing the rubber flex disk and a few other bits (center bearing, etc.) on the drive shaft. If I remember right, some of those jobs require a very large adjustable wrench, which I have.
