right lets try again the axle has ridge running round it that goes to the drive side.the bit that screws onto this then runs on the bearings .does this part need to be screwed on the axle fully to the end of the threaded part.then tighten the other side till smooth and lock with lock nut or can this part on the right be left not fully tightened ,will it move on the thread as pedals go round?any better
?
