    Hard to see with by eye. Usally if something is bent it will show up on a alignment rack. Some of the angles that are not adjustable like set back, toe out on turns, thrust angles, and center line will be out of wack. If a alignment specilist cannot get your caster, camber setting in a acceptable range it may indicate something is bent. We commonly run into a bent steering knuckle in a case like you discribe. Not nessasarly a bent sub frame.
