yes and yes

 

Seals themselves are in between the differential housing (aluminum) and the axle tubes (cast iron)

 

Does anyone have the part# for the seal?

 

It is M48934.

 

Thanks for everyone's help.

 

Can I take the axle/axle tube assembly off the differential all together or do I have to take each off separately?

 

you can see here how it is done when I swapped them onto a 2 speed diff
