Question about 1998 Jeep Grand Cherokee
You can usually locate a good used differential for between $150 and $250. New units are very expensive. It isn't a terribly difficult job if you have a half-way decent set of tools and some time. It takes about a full day to do the job on the ground and far less than that in a shop using impact tools and supports. Labor rates from area to area and shop to shop vary but I'd guess that it should not take a decent tech with the right equipment more than 4.5 hrs to complete the work.
If you decide to do this yourself, decent instructions are contained in chilton and haynes manuals. The only really hard part is if you have any severely rusted hardware which can be a pain to remove.
Make sure you get the correct gear ratio to match the one you removed. You can determine that either from the tag on the cover or by counting gear teeth. (ring divided by pinion = ratio....usually is something like 3.73 which is most common but can be different)
Good luck, whichever route you decide on!

I had the same problem and found a simple, cheap solution: do without front drive (remove drive shaft to front differential, use only RWD). If you don't really need the 4 wheel drive, you'll do fine with only the rear wheels driving the car. I live in NC and do no off-roading, very little driving in snow. I'm fine without the 4x4, for now anyway. It's barely noticeable, except for the loud roaring noise i no longer hear.
