Default Can I use Valvoline SynPower 75W90 Gear Oil in differentials?

Hey guys....sorry for all the questions.
I searched this forum, and found no clear answer about what differential fluid we are to use.
I thought we needed 80W90 differential fluid for the full sized 3.5 Monteros. Am I correct in this?
I have the 2002 Limited, so I assume that the rear is Limited Slip, so can I use the Valvoline SynPower 75W90 for both front and rear?
I just want to make sure I get the correct fluid before the change.
Also...how many quarts for the front and rear?

Thank you for all the help.

You definitely can use it in the front diff and in the transfer case. Does the Valvoline say its compatible with LSD? If so - go for it.

Thanks so much!! It does say its LSD compatible.
What weight do I use for the fron and rear diff's...and what do I use for the transfer case?

Thanks again for all the help.
