Great video! Thank you for including the torque specs. I look forward to seeing more 5th gen ram footage.

What made you add additional friction modifier? From what I understand that product already contains modifier

[@winniedoesyoutube]

I did not add additional friction modifier?

[@dinokarakostas4246]

what made you go with 75w 90 for the rear. I saw another video the guy used 75w 140.

[@winniedoesyoutube]

I consulted the service manual and matched it with the axle in my truck. I believe the 3.92 LSD is the only one that calls for 140 weight, though, so not a very common application. Mine called for what I used (3.55 conventional axle).

Will this work for the cummins 2500

I would imagine that fluid type and capacity could be different. In my experience, some diffs have drain plugs, others need the cover removed to drain the fluid. A Haynes repair manual is where I always start, most local auto parts stores carry them-and torque specs should be listed there too

There is also a additive that needs to be applied for the clutches. Let’s not forget that. Check your owner’s manual

[@winniedoesyoutube]

If you have a LSD, you need the additive! I have a conventional differential so no additive is needed. Sorry if I didn’t clarify that in the video well enough

Those plugs were awful loose and so easy to get off…hmmmmmm

[@winniedoesyoutube]

Yup, loosened them off camera to make filming easier
