Thanks...Oil at the nipple/carbon connection did nothing...for the noise.
I really tightened down the skewer and the noise went away.
Could it be too tight?
The bearings are sealed and as I turn them in the hub they seem to make a little noise. Do I replace them or remove the seals and grease?
I've removed seals on skateboard sized bearings with success (low rpm) but these are different and smaller and might spin out the grease on my blistering rides.
