5th Gen Ram 1500 Differential Rear Fluid Change (2019, 2020, 2021, 2022+)

[2020GraniteBH]

Thank you all appreciate the help!!!

 

[2020GraniteBH]

My build sheet just says "conventional differential rear axle" so just to confirm this mean that I DO NOT need the friction additive when I change the diff fluid correct? Thanks again for all the help as this is all new to me, I really appreciate it!

That is correct!

That is correct!

Thank you!

What are the torque specs for the plugs?
How much 75/110 gear oil is required to fill the diff? (You had two bags out to start the video but couldn’t tell)
Recommend driving the vehicle to warm up the oil prior to changing out?

Thanks for the video - looks straight forward and will be doing this before colder weather sets in Up North.

Front is 2.3 pints, rear is 5.7 pints.
Or 1.15 quart and 2.85 quarts, respectively.

These quantities are the same, regardless of which gears/oil weight you have.

EDIT: Forgot to give credit to the source, Amsoil. I've seen it elsewhere as well, but fastest way to find it was Amsoil's site.

Thanks for your help @UnloosedChewtoy and my apologies to the OP who clearly called out on the video that 3 quarts are required for the rear diff fluid change. I couldn't find the Amsoil Bags so I went with Mobil1. Rear diff fluid level was definitely low as there was no drip once fill plug was opened. Probably just imagining this but I swear the drivetrain is quieter now...

Knocked this out in 15-20 min - very simple process thanks to the contributions here.

Do ya know why Amsoil recommend Severe Gear 75W90 for the front? I got 3.92

The manual calls for 75W90 for all front diffs

Only the 3.92 rear calls for 75w140

True, but the question was about the front diff. Its 75w90 in the front no matter what gears you have.

We’re saying the same thing

Manual calls for 75W85 in the front diff.

75W90 likely works just as well.

Yeah...I almost did that to be exactly correct...Honestly it's not going to make any difference anyways.

my build sheet just states 3.92 rear gear, nothing about limited slip. Still need the additive or is the 3.92 the limited slip?!?

 

[Evoking1230]

nevermind, I can't read y'all lol. I must of skimmed over the "conventional rear axle"

When in doubt, add the additive. It has absolutely no effect on non-slip differentials, but will make a night and day difference in limited slips.

Not to bring up a old topic. I have a elocking 392 rear. If I’m reading the chart correctly that doesn’t get the friction additive? Is that correct?

 

[Chris3058]

Limited slip needs it. You can always add it if unsure as it has no effect on a non LSD but required for a LSD. Someone up above mentioned it.

You are correct. The e-locner does not require the friction modifier
