I have a SRAM Truvativ Elite crank which is wobbly on the drive side only. I pulled it apart and first checked for all the correct parts, and they were all there. I cleaned, lubed, and re-assembled and the wobble was still there. I pulled it apart again and check the BB which seem to have no vissible wear. When apart the drive side has the same wobble as when it is assembled on the bike. I understand the left side tightens the whole assembly but is it normal that when apart the drive side "axel" wobbles independently of the crank arm?
