12-bolt Eaton HD posi ...NOOOISE!!!!!
DO NOT PUT SYNTHETIC in your Strange 12-bolt if you have the Eaton HD posi unit option!!!!! It will cause your rearend to sound like it's coming apart.
Believe me, I have had my rearend COMPLETELY disassembled twice ... finding out the noise is caused by synthetic fluid. Eaton warns you against using synthetic fluid with the kevlar clutched HD posi. DAMN! I wish I had remembered that when I had my Eaton HD unit in my old 10-bolt!!! Anybody else learned this hard lesson? Hope this helps if anyone is having different noises coming from their pumpkin with a HD Eaton posi.

Dude ... mine's a noise like unlubricated polyurathane bushings squeaking when slightly turning right or left at slow speeds ... and a little gear clattering when turning slightly, as well. No noise when I turn hard or on straightline accelerations or decelerations ... and there's a whistling like a jetliner coming in for a landing. It's definitely coming from the center section.

A straight weight 140.... and not a multi-vis either.
My personal recommendation would be for a Schaffer #209, straight weight 140 with the suspended moly... and 4oz of Ford Motorsport friction modifier, if you can still get the older stuff. I believe the part number is: M-19546-A
