99 GC Limited: Growling noise from rear while turning L/R low speed (sound included)

Hi all,

My beloved 1999 grand cherokee limited makes a loud growling sound from the rear when I am driving in parking lots, especially when I am turning hard into a parking space. Reverse / Forward / Left / Right does not seam to matter, just a low loud growling sound at low speed while turning. Straight driving forward and reverse or turning at higher speeds I do not hear it. It sounds exactly like what you here in the included video... start it at 0.20


Anyone have experience with this issue?

Limited slip in rear? Then it needs friction modifier.

The one I miss most is my mind

Its like a fart in a windstorm
It smells good but thats about it

Are you saying to drain and refill the rear dif?

For heavy-duty or trailer tow use:
SAE 75W-140 synthetic
Moparģ P/N 04874469

NOTE: Trac-lok and Vari-lok equipped axles require 4 ounces of Limited Slip Additive be added to the lubricant.

That may help get rid of the growling noise.

Needs the friction modifier. Maybe someone replaced the differential fluid and didnít add the additive? But that will definitely fix that noise.

Thanks, yes it has a leak, I need to do the whole thing.

BTW, I don't know why this post split, I have two that say the same thing, i did not intend for that to happen.
