Backstory: Last year I was testing out a bike for touring and loaded it up a few times with like 30 lbs of weights. I was riding down a hill and the entire wheel locked up and I skidded to a stop. Once home it looked like the axle was bent so I replaced the axle. I rode a few more times and I noticed play in the axle again... and I could not set the locknut tension without too much play and grinding, so I take it apart again and this whole inner freewheel body part comes off. The grease in there used to be pure white so I think it has been grinding away.. and there are a few shards of metal on the end.
Just to make sure, this piece is not supposed to come out is it?
The whole thing:
