My 57 has a positraction differential. How can I tell if it’s low and how often does the oil need changing? Any special type of gear oil for this? thanks for you help.

fins, actually the special oil that RSpring is talking about is a posi-traction additive and I believe that 4 oz. is the amount. It is a small bottle. You can use a good quality gear lube, just put the additive in first. If you aren't getting any clunking or clanking from the rear end the lube is probably fine as long as you verify the level. Good luck!

I use the short leg of an allen key to check the level, keeps my pinky clean. If you are not getting any chatter the fluid should be ok. We use the Canadian Tire brand of posi/ non slip fluid, good day.

I pump it in there to a overfill to where it runs out, once it stops running out the fill hole, the level is correct.

I pump it in there to a overfill to where it runs out, once it stops running out the fill hole down your wrist into your arms and stops dripping off your shoulder into your ear, the level is correct.

The only thing worse is burnt or severly overheated gear oil,,get that on your clothes,,or even stand in the smoke or fumes coming off of that,,and the clothes are a throwaway. stinky stuff, it's worse than diesel fuel.
