First off Glad your both OK
and some little FYI info here,
7 mph is fast enough that if you were moving that fast and stuck your arms out straight and hit a wall, you would break both of them, the human body, on average cannot handle speed and impacts at just 7 mph, many less than 7 too!
humans cannot really handle very much speed at all, or a lot less than most think!
its one of the things, and sayings I hear so often who don;t wear a helmet!
as I am NOT wearing a helmet, as I am not going FAST!
AND all will be OK and well, sadly. it many times is far from the truth! as they just don;t get how little speed it takes for major damage to happen!, and Trust me its no fun to me the one hurt or see others, been there done that way too many times, seen a few die, and some major life changing accidents at SLOW Speeds!
SO< doesn't really take a lot of speed to get hurt or BEND break things!
weight in motion, can be a deadly thing!
NOW< as for your issue
IT is very possible you bend the frame, the A arm or both, , or tied rods or? all and maybe more
toe in/toe out, is not something that should slip easy, if things moved from an impact, its cause something bent or broke!
or treads stripped off something
the key here is going to be jack atv off the ground, and start taking measurements from both sides and try and see what side seems farther out
give atv a good wash first too and look for anything that looks cracked(welds or??) and or bent
