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....

3.5qts in the back if you have an 11.5" rearend 14 cover bolts and make sure you use limited slip bottle I buy mine from Ram dealership if you have a limited slip rearend. Front end is about 2 qts. I use Amsoil 75 90 full synthetic plus a qt of Lucas. and transfer case I always use Valvoline transfer case fluid. it is alot cheaper than a quart or ram transfer case oil at 40 bucks a quart andit takesabout 2.5 quarts there abouts. I have a2013 Laramie Limited Edition 3500. I change my gear oils every 2 years if it needs it or not.

Limited slip additive isn't needed in the rears of 2500/3500's since there's no clutch packs.

Thought I'd read somebody say Stellantis cost-reduced by changing axle suppliers from AAM back to Dana with limited slip clutches? I don't recall what model year, but I'd definitely recommend people paying attention to what their owner's manuals say. For an AAM with a true gear locker, the manual will state limited slip additive is not required (and in fact is not recommended by the axle makers).

Sounds like aam is here til 2030.

I did just read on another site that the 45/5500 uses or used the Dana rear.

I get so confused with manufacturers toggling suppliers often. I'm sure I read something about it somewhere on the Forum not too long ago. I remember lamenting the loss of the TracRite GT torsen all gear differential, and saying something about staying with my 2017 instead of buying new.

Hope I haven't gotten too senile.

up to the end of the production year 2010, Ram 1500s used the
AAM 9.25 rear differential

all 2011 + Ram 1500s used the ZF 235 mm / 9.25 rear differential, ( ZF Friedrichshafen AG )

===========================
i won't swear to this, but

most of the 2500 and all 3500 Rams use Dana 60 front axles. The 1500 Rams and some early light duty 2500 Rams used a 9.25 Chrysler (Spicer) axle in the rear.
A Dana 60 rear axle was used on heavy-duty 2500 V8 Rams.

( some pre 2011, 9.25 differentials were marked )
Chrysler on the Build Sheet, they were the SPICER 9.25s
Others were marked AAM 9.25 on the build sheet

i changed my front and rear diffs to chevron delo 75w90 synthetic. I chose is specifically because of price and also because the Mobil, valvoline, castrol, etc all have limited slip additive, which 2500 and 3500 don’t need. Good luck, not sure if the limited slip with hurt anything. I’m going to use valvoline multi vehicle atf in my transfer case this spring, 2500 with BW 44-47.
