Overlap Triangle

I'm not really sure what happened here. I cut all my oil filters open, and I found bronze the middle of the summer. I pulled the Milodon shaft and gear and it was pretty much chewed up. I replaced the gear with one from Comp. I flushed the system as best as I could.

Damn that sucks sorry. Can you tell me if it’s a needle bearing axle or a bushed axle lifter? Either way it definitely stopped rolling.
