I recently got a used F body sway bar off ebay, looks like a nice piece of work and for $40, so a decent deal. But everytime I see my dad, who likes to question all the stuff that I'm doing, he keeps asking if I've had the bar x-rayed. I know why that would be a good idea, see if the bar has any hairline cracks. Is this overkill? Have any of you ever done this after picking up a sway bar at a junkyard or off ebay?
