Center differentials in 2023.

[bastarddsm]

I've never been a fan of the way most others do 4 spider center differentials. The floating cross shaft is a poor idea, adding 2 more spider gears barely helps. The cross shaft is allowed to turn in the housing, while the gear is held flat against the out side. End effect is the shaft becomes non perpendicular to the gear bore, which can amplify contact force to the point it exceeds the film strength of the lubricating oil. Then we end up with metal on metal contact and galling. I came up with an idea for it many moons ago, and it worked very well. I created locking pins that lock the cross shaft into the center differential body with keeps it from rotating. The first ones used a cross shaft from a 4 bolt rear differential, simply because it fit, and I did not have the ability to make something better. Well now I do. My newest version is much improved over the first iteration. It's a work of art really.

The stock cross shaft is terrible, especially when cut down to use 4 spiders. The peak stress in the drive pins is way more than the expected 2x increase from half the load points. bad, bad.

Is this something that you are offering now, what do you need to make this happen? A good condition stock center differential?

So does this mean you'll be offering this in the Freelancer section? If so, make a post for it there so people can ask you questions about ordering.
