I'm still trying to wrap my head around why someone would leave it in there??? Wouldn't you notice the next time you used the jack???!!!

Maybe it belongs to a shop. They didn't notice it was missing until he was gone. Probably scratched their heads for a while as to where it went, if they ever did figure it out. Who would think it stuck to a control arm? lol
