Driven flange wear normal?

[Happytrails]

I removed my rear wheel from my Wing and pulled the driven flange out. I have a 5 pin flange and noticed that the PO had greased them up which is a no no. I notice that the aluminum bushings still seem round and not elongated. The pins on my driven flange have sort of a groove to them. Is this just the way the pins are supposed to be? Even in the diagram they have those grooves. So they are just for fitting into the aluminum bushings?

The grooves are supposed to be there:





The bushings however should not be elongated. While you have it out, get a replacement set of bushings, that will help greatly with driveline lash. And while you're replacing those, you might as well replace the rubber shock dampers as well, which I'm sure have hardened over the years.
