Hi everybody, another new guy here. Really love the forum. I'm on my 3rd third gen now, all Pontiacs. Getting some great stuff off the forum. Anyway, I'm not sure if I'm allowed to post links I have no control over but I'm sure I'll be deleted if I'm not. I found a link to a great PDF on GM drivetrans. I believe it is from a GM service manual. It's about 250 pages long and has all the info on rear bearings, seals, gear setup etc. I find it quite helpful at times. Heres the link.
