Thanks to everyone for the replies. Bruce88123: I will test this out tonight when I'm back home with the plane. It seems to me like there should not be any binding issues becasuse once I move the stick away from the most extreme throw (even the smallest amount like 1/32 of an inch) then the noise goes away. Therefore, if there were a binding issue I would think that adjusting the travel down to 75% in the radio would certainly solve that problem.
I'm wondering if this is a weird function of the radio (DX6i) when the sticks are pushed to the extremes? Or maybe this is due to having cheaper type servos (Futaba 3004)?
Either way, I will disconnect the pushrods tonight and make sure they travel freely.

You still have to much throw dialled in ,in the transmitter and the servo is moving the control surface too far and binding.
Cheers
You have no idea of how much throw he actually has. While this MIGHT be the problem it is far from conclusive from what has been stated so far.
Hawes99 - how many degrees of defection does the surface have? If you disconnect the pushrod from the servo does the pushrod/elevator move freely through your desired range or does it tend to bind? Try to keep the pushrod at the same angle when testing as it is when connected.
