I bought some Gear Oil Mobil85w-140 for my Differentials. about how much should i put in each one of the Diff. Also Is this hard to do I also bought a manual pump because i heard its easier that way.

I bought some Mobil Synthetic grease for the bearings. Is this ok or do I need regular grease.
thanks

 

You can use the grease for your u-joints, everything else is sealed.
As for the gear oil, 1.8 quarts for each diff and 2.2 quarts for the t/case.

 

Fill the diffs and transfer case until the gear oil starts to come out of the fill hole.
Replace fill hole and you are good to go.
That grease is perfect.
You will need 8 quarts to fill everything.
