A sound came back and I put on new cleats on my shoes and it went away. The another sound developed which was bearings in a pedal where shot....New pedals. I've also had the rear quick release a bit loose at times cause a clunky grindy sound when you're really putting the power down. Tightening the quick release fixes that. My bike is grinding again now, I think the BB is dead again.
Clunky creaky sounds are notoriously hard to track down as they can vibrate through the entire frame and sometimes aren't actually coming from where they sound like they are.
