7 1/4 diff pinion oil seal replacement question.....

Looks like I may have a leaking rear pinion seal, but after looking at some videos & reading the R&R instruction on this page, it looks to me I just remove the 4 U joint cap nuts, then the u joint caps, then the infamous nut.. Mark location, count number of times it rotates before complete removal. 1 video was excellent, removing the nut & base plate was no big deal, just a lil light tapping with a hammer, no need for a puller. Guess Ill find out when I get into it.

This is the OEM Ball & Trunnion drive shaft.
