It really isn't that bad, you need a pinion seal. As far as installation and removal goes it shouldn't be too hard, you have to take off that huge nut/bolt on the side of the pumpkin where the drive shaft bolts up to and get a seal puller and pull it out or you could pull it out with needle nose pliers too.

JUST MAKE SURE WHEN YOU TIGHTEN THE PINION NUT BACK UP YOU HAVE THE CORRECT PRE LOAD,IF NOT YOU WILL HAVE A PROBLEM.

Mark the position of the nut in relation to the pinion threads before you remove it.
Reinstall the nut and tighten untill the marks line up. don't over tighten!

hope that just the seal is bad! in my case i had a leak from the seal but not becasue the seal was bad but my front pinion bearing was shredded and my pinion was floating off the ring causeing the pinion seal to break. all kinds of metal shavings in my diff caused pitting of the spider gears and ring gear. tranny shop wanted 1600 to fix it. i decided im just going to replace the whole rear end from a pick n pull for half this price

Ouch, I did the same thing, I went and pulled a rear end assembly. It was better that way because I redid the brakes completely, put some new axles in, and I am currently waiting a week or two before I order my locker and 3.92's or 4.10's to throw in there.
