2008 H2 Hummer.
Hi,

I replaced the oil in the front and rear diff and noticed the levels were very low.
Take a look at the pictures below.
These are the actual amounts that came out from the front and rear diff. I am more concerned about the front diff seeing that it had only 1+ Litres of oil. The rear had 2 1/4 Litres

Hmmm... If you don't have signs of leakage, no unusual noises, etc..., then I would refill them and count my lucky stars. Seriously, unless there's a leak there's nothing you can do about it. Good luck!

 

You refilled with some great oil. I bet you will be fine.
