Rear differential confusion- and how much and what type of oil?

diff.
Hi Well for years I felt sure that my 2001 dodge ram 2500 has the limited-slip diff. so I applied the friction modifier. If it doesn't need the modifier I don't know if it will do any harm. I just learned that it has the corporate 9 diff. but I am still not sure if it is LSD or not. The sticker under the hood says that the ratio is 3.92; page 1 of 1 4stars and then the num. -0370780. What is t.o.n 61310348?

Yes but I have hard time believing a 01 2500 came with an 8 lug Chrysler 9.25 rear. Based on what I have seen and the info I have read the Dana 60,70 or 80 where the only rear axles they put in the 2500 in 01.

You would be correct that the Chrysler 9.25 8 lug wouldn't be in an 01. But someone could have changed it not knowing about the LD and HD models
