Rear end Fluid??!!?? i did a search and read up on different kinds of rear end fluids, yet im still confused on what kind to use. i have a moser 12 bolt with 4.10s, should i use a synthetic blend with the additive, just the regular stuff with additive, or just the regular stuff without the additive(i read on another post that it can mess with the clutches if you put the additive in). 
Also do you recommend 75W90 or 75W140
THANKS

Which diff do you have in there?? I'm guessing an Eaton cf posi since you mentioned "clutches", but don't know. This is what will determine the fluid and/or friction modifier additive.
