Do you have a limited slip rear diff?  You should be able to tell by
looking at the rear end and seeing a tag attached stating the use of
friction modifier needed (or special fluid, something to that effect).
Also check your manual, see what it says about a limited slip or
"locking type differential" as my manual says.  You may need a fluid
change on it.

I had a similar problem on my '87 Grand Wagoneer, the rear diff makes a
bit of noise when warm.  As it turns out, changing the fluid & making
sure the correct fluid for a limited slip is put in helped solve the
problem (although mine is a bit older & much more worn out!).

Good luck,

Unfortunately they put an aluminum rear end in some of those that is
extremely hard to keep wheel bearings in.

If it ever gets jacked up by the pumpkin like some tire shops like to
do, it will get destroyed usually or bend the tubes enough that you will
never hold a wheel bearing in it again.

You should look for this aluminum housing.  If yours is steel, ignore
the above and check the fluid level or the fluid for water contamination.

Tell jeep to keep it until it's fixed if they don't use the Lemon Law,
it kinda sounds like the limited slip diff is acting up.
