the fact that its not centering right. you obviously messed up the gears during the crash.. go buy a new gear set

the fact that the servo humms is its constantly trying to center..
every one of my digital servos do it. none of my analog servos do it..
i have around 10 digital servos.. all from hitec


That pretty much sums it up.
In a 2 servo setup where the servos are ganged to each other the only true way you can see if they are fighting each other is to measure the amperage draw. Simply listening to the servo will not tell you 100% if your setup is ok or if the servos are binding.
As for my knowledge, it comes from my 17 years of experience in this hobby. I can understand how light poles seem to jump out of no where though.
