2005 Jeep Grand Cherokee 5.7L Hemi

After driving on the highway for an hour or so then parking my Jeep, I
hear a loud vibration/groaning come from the rear of the Jeep when I
drive it again. It only happens when I steer left or right. It
sounds like the rear of my car is about the break off! Usually, after
making a three-point turn (or any sharp turns and/or putting it in
reverse), there will be a loud pop and the vibration goes away. Does
anyone know what might be wrong?

Chrysler-Jeep doesn't know what's wrong because the vibration usually
goes away before I can get it to them.

Thanks for any ideas!

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,
