[Dangerous Doug]

I have the ERA rear.

I didn't see any play between the wheel and the 3rd member stub axle. I could, however, see play between the stub axle and the bolts on the driveshaft. This tells me the play is in the 3rd member.

In retrospect, I'm not sure this is the source of the sound. Might have been that beer I was drinking while I was working on it last night.

Chassis dyno. Good idea.

I'll take it out for a diagnosis ride tonight. I had checked each of the calipers last night (that's where I started), and they were tight and the pads had minimal movement/sound.

Need to find a quiet slope to coast and listen to the sound again.
