A couple days ago the old bike developed an audible and periodic creak. I've narrowed it down to the crank/BB area. The parts are fairly dated - a few years old I'd say. Suntour crank with riveted rings and a brandless BB. The creak makes itself known at the top of every pedal stroke on the drive side. I can feel it in the pedals and its loud enough to hear. I cleaned off and lubed the moving parts without taking it apart but the creak persists. Anyone have an opinion?
Thanks for the suggestions. Took the pedal off and apart to find one of the bearing shells was crushed. Literally fell out in chunks when I took the cap off. The rest of the bearing sticks off the spindle in jagged edges so now the pedal doesn't quite sit level while under pressure and the creak persists. It only happens when the drive side pedal is under pressure (which is now understandable). After a few tests, the crank/bearing seem to be in proper working order.
