I have a problem here. So I have been having a problem with a creaky noise in the crank/bb area. I have had a lot of trouble trying to pinpoint the source. I have replaced the BB and taken apart and relubed everything else. I just recently saw that my drive side crank has some play in it ( you can move it in towards the frame and out again with your hand. I have a Truvativ Rouleur crankset. Today, I took the spindle off of the drive side crank, cleaned it, and put it back together using a rubber mallet to make sure that it seats itself as much as possible. I put it back on the bike and it still makes the same motion.
I am 90% sure that is the source of the creaking noise and even if it isn't, this is still a problem. I would like the diagnosis anyone has and what can be done to keep my crank from moving in that fashion.
