Agree, no synthetic! If the customer insisted, my friend would warrantee his work for six inches/six seconds, which ever came first.The guy who is building and setting up my cone type diff advised against using any synthetic lube. I am having an Auburn installed on mine and his exact words were "Auburn cones don't like synthetic" and he has been in the business over 40 years.

That may be true. I'd run it anyway.Was always told that cones types do not require friction modifier?
Friction modifier is for clutch plates. no clutch plates = no modifier.That may be true. I'd run it anyway.
Agreed.Friction modifier is for clutch plates. no clutch plates = no modifier.
If it doesn't chatter. I've had some that did and some that didn't. I've tested out several over the years without the modifier and more than half of them didn't......I've heard that also.

I have synthetic in a fresh Dana 70 that's supposed to have friction modifier in it already and the LSD chatters....and the gears have a faint whine from 55-65. Not many miles on it yet so I'm going to drain it and stick in regular gear oil and modifier. Did some research on it before doing it and well, there's about a 50/50 thought mix on the syn vs regular lube.Agree, no synthetic!

Are you saying that if it Cheddar's you should use friction modifiers? Cheddar'sIf it doesn't chatter. I've had some that did and some that didn't. I've tested out several over the years without the modifier and more than half of them didn't......
Why would Auburn recommend modifiers for the cones?If it doesn't chatter. I've had some that did and some that didn't. I've tested out several over the years without the modifier and more than half of them didn't......
The modern day Auburns are different than the factory style Borg Warner units but I don't know exactly how different they are. Have heard some complaints about them and also hear they're not as good as the original factory units. If Auburn recommends it, it's probably for a good reason. I have run some stock BW units without the additive and didn't see any unusual wear in them after a couple of years of pretty hard use but I'm also one that isn't going to abuse an LSD by nailing the gas when the rear tires are not on a similar surface.....ie, one tire on hard surface and the other not. Imo, that's one of the worse things you can do to one.Why would Auburn recommend modifiers for the cones?
