Hyundai Repair: 2001 XG300 click/clunk when accelerating.., tone wheels, wheel speed

Question
I have a 2001 XG300 that after you are at a stop, you start accelerating and then you hear a click/clunk (almost a binding noise) around 10-20mph, it happens as you accelerate.  It sounds as if it is coming from the driveline, not tranny. I turned off the Traction control and it has seemed to go away.  What would cause this?  Any ideas for me to look at/replace?  

Answer
My top suspicion is that one of the tone wheels (the ring that the wheel speed sensor reads) is damaged, cracked, or broken.  This could cause the hydraulic module to think the wheels are slipping, causing the traction control to engage.

Also, check to be sure all your tires are the same size and properly inflated.  In some instances, use of the temporary spare results in TCS issues if the TCS is left on.
