Rubicon differential sump capacities

I changed the differential oil today in my Rubicon unlimited. I filled them from a container with a pump on it so I didn't keep track of how much went into each differential but the rear seemed to take more than the front. The manual has no capacity listing for the diffs that I could locate. Anyone have an idea what the fill capacity is for the front and rear?

2.7 pints in the front and 4.75 pints in the rear fo the Dana 44 axles.

The Dana 30 fronts use 2.1 pints.

Here are the factory differential capacities for the JK:

FRONT AXLE ± .03 L (1 oz.)
186 FBI (Model 30) 1.0 L (1.05 qts)
216 FBI (Model 44) 1.3 L (1.35 qts)

REAR AXLE ± .03 L (1 oz.)
198 RBI (Model 35) 1.83 L (1.9 qts)
226 RBI (Model 44) 2.25 L (2.4 qts)

Actual amounts from factory on my vehicle:
Front Dana 44: 44oz (15oz above bottom of fill hole) (1.4 qts)
Rear Dana 44: 72oz (slightly above bottom of fill hole) (2.25 qts)

The rear takes more because there has to be enough to flow to the outer axle bearings.

jk's dont come with dana35's

the D44, locker or no locker, is a little different due to the rear locker. the axle shafts are different lengths slightly
the regular D44 with no locker the axle shafts are the same.

The very first run of JK's (non Rubicon) in 2007 model year came with D35's in the rear. This was only done for the first few months of production then was changed to D44 rear as standard equiptment.

On a Rubicon or any modle for that matter the front takes less oil because it does not fill out the axle tubes as it does in the rear.
