i thought it was 2.8 for the front and 4.6 for the rear or somthignlike that. OR you can jsut do the finger methond and fill it till you get to the Fill Hole then drive around the block and stick your finger back inthere. I think thats the easiest way. As long as its up to the fill hole your fine. My front took 2.6 before it spewed back out and i have the arb. I havent done my rear yet but advanced says it takes a little more then 2.6 not sure why might be the angle???

I did my Riddler rear diff cover yesterday, the factory spec is 2.375 qts. I actually put in 2.6 qts. because there is a little more volume inside with the design of this diff cover.

The important thing with the rear diff is the fluid level is high enough to flow to the outer axle bearings.
Whatever the location of the fill hole, (some after market covers have a much higher fill hole), the fluid level should be a little above the bottom of the axle tube.
You can check this with a homemade "dip stick". Make one from a bent zip tie, for example.
With this information, you will have the correct amount of fluid in the diff, no matter what cover you have, or what anyone says the published amount is.
