I think he is being resistant and trying to show dominance over you or he is trying to show you how unhappy he is...you said it yourself that he is refusing to canter on the lunge....doesn't sound like a happy respectful guy.
I have often heard this sound with many of the geldings when lunging just because they are excited to be out of the stall, etc.
Check your horses sheath but don't go crazy, cleaning it with chemicals too often can do more harm than good. Also, he would be rubbing on his rump not making noise when excited if he had a bean or something that needed to come out. Good Luck!
