Rear End Growl
I just bought a lifted 1999 Jeep Grand Cherokee with a serious lift and 33in tires (LT285/75R16) I had to put in $1400 in front end work to stabilize my steering, it kept shooting me into the ditch or what ever direction I was steering when I turned the wheel sharp in that direction.

My question is, at slow turning speeds 1 to 2 miles and hour, I'm getting a sound from my rear end that sounds like mud flaps rubbing on the tires nobby's. But there is no tire rub on anything? It's a low growl, that I'm thinking is coming from my rear gear box but not sure. It only happens when I'm turning, left or right. When I'm driving straight, no sound at all.

I would be willing to bet that sound is your differential/s. When was the fluid changed last? I would suggest changing the fluid in which ever diff you think the noise is coming from. What axles do you have? I'd be willing to bet the rear is a Dana 44. If that's the case you MUST add the friction modifier to the gear oil! This can only be purchased from your dealer. I get it from my stealership for $10.50 a bottle. That should kill the noise you are hearing.

I did get my fluid changed again and wouldn't you know the sound went away. You definitely need the limited slip additive. What I had learned is the mechanic before only thought he added the additive. Major pain because when you ask point blank about the additive and he says that he added it then you belief him. After changing the oil and about a 100 miles things are getting back to normal.
