Eaton limited slip differential - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Tpo** · 02-12-2024, 02:41 AM

So if I’m to believe the sticker behind my gas tank, my 60 half ton 2WD has a limited slip. After an hour of reading old threads I think I actually know less than I did before I started. Do I have clutches in my carrier that need a posi additive? Can I run old school 80/90 weight gear oil, with the posi additive, and be OK? Does it need to be hypoid oil? I’ve yet to drive it so I don’t know what kinda shape the rear end is in, those clutches may be totally shagged by now.
Thanks!
