When I was running my maxx the other day, I found my RR wheel a nit too wobbly for my liking. After my run, I took it apart and found the inner bearing all messed up. It was so messed up, tiny ballbearings fell out. I replaced it with a new one and also changed the outter bearing. Much better! it happends to be where the clicking noise was comming from.
this is whats left.
