Sounds like you missing teeth on your pinion/ring gear. Time for a rebuild or upgrade...

Only way to truly know whats going on there is to take off the diff cover and look.

So many people to thank here's a start to the list
Spidertrax, Yukon, rustys, warn, branik, PSC, advance adapters, Bad wheels, interco, essentially off-road. And many more

Most of all thanks too Ian Johnson and the xtreme off-road crew for all their work, and 4 wheel to heal for their part in it too.

You shouldn't need more than 2 hours to do the inspection.

Now depending on what is wrong inside, 2 days might be a good estimate for repair time.......

I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.
