Does a 14 bolt full floating rear with factory locking diff use GL5 80w90?
The guy at the part store said that's what to run. I couldn't find anywhere that specified locker or open so that's what I'm doing.
The G80 in the 14 bolt does not need any kind of additive as far as I know. Mine is open, but I also just run standard GL5 80w-90
Thanks for the reply. I can't find much info on the locking rear.
