What are you guys using for gear lube?
Eaton calls for Non Synthetic and no LS additive.
You know how hard that is to find.
I had to end up buying Lucas and it still had LS additive.

I use valvoline gear oil with great results. I've got truetracs in both ends and I wondered the same thing. The only stuff I could find was lucas, coastal, and valvoline. I change about twice a year because I do a lot of wheeling and pretty regularly submerge my axles.

I put truetracs in front and rear and re-geared a couple of months ago and struggled with the same question. Read all the reviews I could find. Ended up using Advance Auto Parts house brand non-synthetic. No LS modifier in it and meets all requirements. Also a lot less expensive. So far I've not had any problems with it.
