Hey, how much room so you have for a thrust bearing? I can cut a CF washer on my CNC for you. CF has a very slick hard surface that works well as a thrust bearing when there is not enough depth for a normal thrust bearing. I have done it with decent success.

The bearing itself is 8x14x4mm. Each Pinion uses two of them.

How it's setup now, the front pinion tries to push into the front diff, while the rear pinion tries to pull out of the diff.

Maybe just use CF on the load bearing side and a Ceramic Nitride bearing on the free wheeling side of the pinion. Think that would work? It sounds good.
