New chain and new cassette. I didn't think it was the back end because I could get it to crack at the bottom of the pedal stroke. It probably is the spider but needs more resistance in place. Stupid bikes.
skewer tend to creak but not at specific point in the pedal stroke. Cracks or creaks at particular points in the pedal stroke is more likely than not to be pedal/cranks/bb but never rule anything out including your knees and hips.
