After replacing the rear boots with factory stuff, and doing the rear brakes I started getting a clicking that would come and go. Could not find any cause but I did remove the right rear (sound came from this side) and noticed the rotor didn't look like it was square with the axle. It did move about 1/4 inch and then looked right. Put the wheel back on, and no more click in over 5000 miles.
