Question Eaton True track rear diff

[Brian3676]

I have a 2009 F 450 with the 6.4L. Currently have a Dana S110L limited slip diff. I want to put in a Eaton True trac rear diff, However Eaton is telling me they are not sure if it will work due to the oil differences. It will psychically fit, but possibly not work. I see my truck uses a synthetic from the factory, and Eaton tells me unless I put a regular oil in with there diff, then it will not lock up. So since I am swapping out the diff for the Eaton, can I use regular oil? Or will that destroy the bearings and other components on the rear end?

If it's the one I'm thinking, it uses helical gears, not clutch discs, so the oil wouldn't matter..

If it's the Eaton LSD, then yes, use the oil Eaton specifies. The bearings aren't going to care, but the clutches will.
