Well, they are noisy and I can hear occasional popping at low speeds. The popping seems to go away at higher speeds but I think that it's just being masked by the motor and bearing whine. I tried oil at first and then packed them with Redline CV2 grease. The grease helped a little. I ran them in for about 30 minutes this morning. Compared to the AC bearings they are louder and don't sound nearly as smooth.
