Genuine OEM Dodge/Mopar factory fit part
its the clutch packs in the axle from the quadra drive system. you either need to add friction modifier https://www.amazon.com/Genuine-Mopar-4318060AC-Limited-Additive/dp/B000TTEX8W. I had to do a full fluid change I used royal purple 75W140 with limited slip addative, as well as a little extra mopar addative. sound went away
Doesn't get any better than royal purple, nice choice. I would still recommend a friction modifier, but if you wheel and have to flush the diff out often maybe just skip it. If you don't, and just do normal service this stuff goes in my 67 Jeep front and rear LSD diffs, the rear of my 98 ZJ and my LJ (has air lockers but I add anyway, doesn't hurt)
It's real quality stuff and will prevent it from chattering, one bottle per axle

I have a 1994 Jeep Grand Cherokee 5.2V8, NP249J transfer case, Dana30 front diff, and ?Dana44A rear diff? still not 100% sure about the rear diff model
1994 would have a d35

If I use this Lucas gear oil 75w-140 Synth, which says excellent for limited slip use, do I still need to add this additive when I service the differentials?
That'll be fine, no need for an additive.

Also ATF+4 in the transfer case?
Dex/merc or atf+4. The tcase isn't picky.

How do I tell if my Viscous coupler is bad? Recommendations if it is?
I think the test is to turn in a tight circle and if you feel binding it's bad. Recommend a 231 or 242 swap.
