As some of you may recall, a few months ago, I complained about a loud noise coming from my wheels. It wasnt a full time problem but when it came on, it was LOUD and would coincide with the rotation of the tires. The stealership said that I needed to "glaze my axles" which generated a few chuckles from the forum. A buddy of mine who ran a shop insisted that it was my brakes. But whenever I brought the rig in, the sound could not be replicated..typical! We changed the rear rotors (worn right down - 05 HSE.) and changed all four pads.. but the sound would still persist. Finally, last week, on my 4th visit to my buddy's shop, the sound kicked in and everyone in the shop stopped to look at the rig.. even people in the office heard it. They were able to replicate the sound manually when it was on the lift. In short, the brake drum was not perfectly round. My buddy said that this was common when drums heat up. It wasnt warped but enough to cause metal to rub on the hub. So they machined it down. A simple fix. No cost. The stealership was going to charge me $150 to "glaze my axles".... fyi, in case you get a similar sound.
