Guys I need your help. I am changing the dif fluids front and rear. Going with Mobile One as it has never let me down. Question is how many quarts does each diff take. I checked my truck and the owner manula is gone. Also what does the transfer case use for fluid and what quanity? Thank you in advance.

Should be around 2-2.5 in the front and 4.5 in the rear for the HDs. You can use the Amsoil website to get fluid capacities for your specific truck. I'm not advocating the use of Amsoil, but it's a good tool on their website.

Plus you get to do some math!

I'm advocating their fluids and their site for capacities.

I recently did front and rear diffs on my 2016 2500 6.7 and it bought 4 quarts for rear and 3 for the front to do the job with standard differential covers. Some after market covers add more so if you have them check with manufacturer and add that on to oem amounts. I did have a little left over for each one, but these quart amounts on OEM will make sure you have enough by being into the last quart when filling.

Transfer case just loosen top nut first, do not over torque any transfer case nut, those cases will crack. That's all you need to know, unless you remove cover to scrap, all of those items are just tighten bottom nut after drain and fill til it drips, done. Just order a little extra, it stores well. I don't know what m1 is correct for that t case, redline c+ or amsoil multi use transmission fluid have worked well in those. The mopar stuff is just over priced fluid, up to you.

redline c+ is in mine, it is however a different t case. Ask @Hemi395 for your question, he has done the work on this. If you want to stay with m1 I am sure there is an option out there, I just don't know it. Agreed their diff fluid is very good if not great.

Which transfer case do you have, one with 4Auto or without? The fluid requirements are different....
