To get to the rear diff you don't even have to jack the car up.
1) remove the spare tire carrier (3 bolts and a screw that holds the wire)
2) put pan underneath the fill/drain plug (there's only one)
3) open plug and let fluid come out. When it stops jack the front of the car up to get more out. When that's done use a pump to get the rest out.
4) lower front and refill.
It's that easy....
As a side I use redline 75w90. That one comes with LSD friction modifiers that the NS version doesn't have. It isn't necessary,but doesn't hurt a thing.
