Good Evening All,

I have a 2019 ram longhorn with the 3.21 gears and the off road group so I have the rear locking diff. I also have the auto 4wd. I am looking for some clarification on a few items before I order what I need to service everything at 60k.

Front Diff takes 75w-85. Is there any special certification it needs? I’m looking at a soil severe gear or valvoline synthetic. How many quarts does it take?

Transfer case - how many quarts does it take? I plan to get the mopar oil specifically for the transfer case.

Rear Diff takes 75w-90. Since it is the locking diff it doesn’t require the friction additive does it? How many quarts does it take?

Lastly, to check the level, is everyone raising the front of their truck to be level with the rear or just using wheels on the ground on a level surface?

Any help is greatly appreciated.

IM NOT SURE EXACT AMOUNTS BUT I USED AMSOIL IN ALL 3 AND USED THE SQUEEZE STYLE BAGS EACH ONE TOOK 2 WHOLE BAGS AND 3/4 OF THE 3RD. I MADE SURE TO MAKE THE TRUCK AS LEVEL AS POSSIBLE AND FILLED UNTI IT THE NEW FLUID CAME OUT OF THE FILL HOLE.
