Im replacing my stock 2010 JKU Frt/Rer diff covers with new ARBs.

Do I fill both front and rear to factory oil capacity or another since the fill hole on factory and fill hole on ARBs are in different locations?

I think I've read that factory is:

Front : 1.5q
Rear: 2.5q

 

Fill to factory specs.

Front Differential Capacity:
2.7 pints (1.35 quarts)

Rear Differential Capacity:
4.75 pints (2.375 quarts)

 

Just did this, added lube lockers as well. No leaks. But wish I painted the covers black before I put them on.

 

Mine are the black ones from northridge 4x4_nice looking.

 

Thanks... Yep they are - looked underneath the cardboard and found the sheet.
