I'm unable to tell if the spindles are bent, if the crank spider arms are bent, if the BB is loose within the shell or... But a crooked in shell Bb with a straight spindle will cock the crank in only one arrangement, spinning the cranks will not produce a "out of true" look as the crank will just not be parallel to the frame's plane.


With out either better descriptions and/or photos showing the issue this is when the LBS is your best friend.


As to the shell's condition- The threads are no indicator of the faces and visa versa. The threads can be cut off axis yet the faces could be parallel to each other and to the frame's plane. But with most modern threaded and tapered square BBs as the spindle is held within the outer casing (that has the drive side threading) and that the non drive side "cup" (actually retaining sleeve) the spindle is far less dependent on the shell faces to sit properly within the frame.
