My crank's been creaking and clicking for a while now, and I just this afternoon took it apart, re-greased the threads of the cups on both sides and cleaned the BB shell and threads in the frame. Turns out the left (non-drive) side cup is plastic! Has anyone had this before? I didn't know you could/would make something like that out of plastic. The bike's not dept. store quality, so I am surprised unless this is just some practice I've never heard of...
The bike is a KHS Urban-X: http://www.khsbicycles.com/06_urban_x_07.htm
BUT the creak/click remains, of course. Given that I've correctly cleaned and installed the bottom bracket, and that the noise still comes from the crank: Would it either be that the crank bolts are too tight or not tight enough?
Or is it something besides the crank bolts and bottom bracket?
