Found out changing the oil in the front Diff was a bit tricky on my 05 wk hemi with quadra drive 2.
So listen to this.
I routed a tube into the fill hole of the diff after draining the old fluid.
Secondly i taped the tube to the nozzle of the gear oil bottle and tipped it upside down, letting it rest on my radiator. From there on the oil gracefully filled itself into the differential through the tube.
Secondly for those of you who want to do this on your own and dont own large allen keys. Go out and buy a 14mm bolt, and some nuts. This worked perfect for removing both the drain plug and filler plug. the bolt fits perfectly into the drain and fill plugs perfectly, all you have to do is wrench it off.
Heres some pictures to show yall what i mean.
Hope this helps. BTW the dealer suggested i use two bottle of friction modifier for each differential. Using One is ok as well
