Agreed! Great input x91j and jjjingle36!
I have had the same problem for at least 3 to 4 years with the "growling" sound only on tight U-turns or parking lot manuevers. Going straight = no noise. Slow tight turns = loud growling sound from the rear differential. (At first I thought it was the front end.) We added the Jeep recommended limited slip differential lube (4oz.) to the rear end differential and the noise went away, no immediately but after about a week of driving. This was amazing as we have been putting up with that aggravating noise for a very long time. The vehicle is a 2001 Jeep Grand Cherokee with QuadraTrack (4 wheel drive all the time). Many thanks to you folks and this web site. I hope my confirmation of this similar situation also helps others.

OK i have a 2003 and a 2004. the 03 drives wonderful, so much so i bought the 04. the 04 does not drive the same. they have the identcal drive system tcase trans and all. the 04 binds and vibrates pretty bad on hard left turns. this is not "Normal" so far i did the diff fluid change with the required fluid and additive, Fail. i did the T-case fluid change, Fail. i did the not fun viscus coupler change.....FAIL. i have had several 4x4s and know what 4wd binding feels like and that is not it. my bronco with a detroite locker in bank and a Detroit turu-trek in front did not do this in 4wd. 4 low in the jeeps 03 and 04 buck like i would expect 4low to do but in awd they both are totally different

Yeah i have read responses to this issue and several fix ideas. so my 04 150k miles, turn hard left but not right the body shakes and feels like the tires are fighting each-other and on pavement you can smell burnt rubber. i also have an identical 03 with 170k on it that i have had 2 years now. it does not do that...at all. yes the awd works well on the 03, we get snow and it was fun. so the "its normal awd operation" is false. when jacked up off all 4 no problem.

so far i did
Differential fluid change and additive. Fail
Tcase fluid change... fail
the pain in the butt Viscus coupler change at $380.....fail

still no change at all. taking it to the shop to have them go over it next week. we are thinking its the differentials themselves.

my last wheeler had a tru-trek in front and a detroite locer in back. turning at full lock it would buck but nothing like the 04 groans and vibration.

if it's coming from the front does it have 4 wheel drive or just rear wheel ? 4 wheel commonly the hubs rust or the transfer case locks in low 4 wheel , problem with my 01 jgc limited , or hub bearings or brakes . then makes a rubbing type sound on turning if it's 4 wheel you could take the immediate shafts to the transfer viscous coupler out as well as the vc itself making it rear wheel drive only , other then that check your brake pads n rotors for normal wear and your hubs for wear or broken hub /worn hub bearing if ones bad on that get 2 don't just replace one or you'll have the same problem from the other side of the SUV later on if it's the back more then likely hub bearings going out or went out bearing puller and new bearings should do the truck there .

UPDATE mine was solved. it was the parking brake dragging. i took the rear rotor off and had to lossen the Ebrake to remove it and all my problems were gone. hit the Ebrake a few times and it came back. took it to a shop and they took care of it.....but have since sold it
