Well,, test was done and it passed with flying colors on my truck,,, in fact, I bent the arm on Jack instead of hitting steps on opposite side while turning other direction accidently because of Jack arm being turned wrong way,,,lol,,,,zi needed to replace it anyway....zi bent it back, but it's still binds as bad as it used to,,,just time to replace it I recon after twenty years of abuse,,,Steps though work great,,, I can see where on maybe another truck or car it may interfere possibly,,, but It'd be a miss on first step and close call on second step if it could turn that far....
