2011 Ram 1500 4WD 5.7L Hemi Differential(s)?

[Aurelius]

Do both of the differentials (front & back) require fluid? My guess is that they both do, but I'm not sure. I know I have a transfer case that requires fluid.

The owner's manual says: "Front Axle 1500 Four-Wheel Drive Models" in the list of fluid specs. It doesn't say: Front Axle & Rear Axle Four...

How often should these fluids be changed? I bought her new in 2011 & she has 44K miles; I haven't yet changed these fluids, but thought I would in the New Year along with changing the original plugs.

Thanks for the help,

Steve

Both require fluid, here you go for reference.

I’ll try and find you change intervals and capacities in a bit.

^^^^^ This----Do you know if you have a limited slip rear diff?

Thank you both very much. Rear slip differential? & to think, I just found out that I have 16 spark plugs! Jay, how would I find out? I will look on original invoice & if that doesn't know, I'll Google the VIN & see if that provides the info.

Put in your VIN and it’ll give you your window sticker, see if it says “anti spin differential”. If so you need the Mopar friction modifier, limited slip modifier
