First off, I want to say thank you for your reply. I was beginning to think there was a secret handshake I missed here.
Just a constant squeak. I have listened closely while going over RR tracks and bumps and there are no noises, just that dang squeak after about 25mph. Nothing that I do (turns, brakes, bumps) changes the sound. I hit a couple of the bushings that I could reach with the wheel on with some liquid wrench and nothing changed.
Is there anyway to test the hub/bearing for noises, beside replacing it and hoping for the best?
