Hey,
I have about reached the end of my rope.
I don't know the what search criteria to use to find what lubricants needed for the differentials (both F&R), transmission, and transfer case. I'm almost positive I had read about them here on FRF, and believe I watched a video or two on the subject, but that was also back when I was a bit more active on the site (Maybe in 2014?).
I apologize for bothering you with this, but it seems like you & ChrisFixx are like brothers
Thanks for any help you can offer.
