I just picked up a dawes kingpin (3 speed SA) and went to service the hub but it now (didn't test before) makes a noise when freewheeling like a dry bearing scraping sound.
I had cleaned out, re-oiled, re-greased. The internals were completely dry but minimal surface rust on the inside shell. cone bearings look basically new and were full of relatively new grease, no scoring on the cones. I didn't see anything wrong inside. The bearings that sit under the driver were a golden colour, maybe lost their coatings?
Sidenote: the drive size cone was originally over 180 degrees wound out with lots of play in the cone, sheldon says 45-135 degrees. I have set the cones correctly.
