Oh I wasn’t trying to argue his point, he is correct. Was just trying to help prevent people buying these great tools and using them without reading the manual. Undoing the wrong part of a bolt/but or trying to force undoing a reverse thread with that much grunt is going to cause problems.Play nice children, your both right. The fronts are one way and the rear arm to frame bolt is opposite of the two front bolts.
Also, it’s worth soaking stuck fasteners with some sort of penetrant and leaving for a few hours rather than just going straight for the impact wrench...
