Need Help Finding Cause Of Wear in 92 Astro Van Differential

I need help understanding what would cause the C-Washer Wear and the wear of the Splines on the Left Axle; that seems to have slightly narrower splines at the inner end.
1992 Chevy Astro Van Rear Wheel Drive 7.625 Ring Gear (wear there OK).

The C-washer is from the Left Side.

The Side Gear wit the Groove where the C-washer rides is from the Left Side.

Both of the Differential Carrier Bearings show a Dark Grey Wear area that looks as if it ran over some small particles and the Rollers have some scoring but nothing catastrophic that would pull the Carrier out of alignment.

The area where the C-washer rides in the Right Side Gear is perfect.
