There was nothing hit or ran over. This started happening after changing out the wheel bearing and axle. I would say the sound is more like a rusty bed. I would say that it was the shocks and struts, but those were also replaced. If it was metal rubbing, I would assume that the sound would sound more like a scraping and increase in volume due to the expansion that would occur because of the heat. It would not go away and keep occurring throughout the day.
My best guess is that it’s something rubber related, because it occurs when it’s cold or raining and goes away once everything is warmed up after driving a little while. I think the only relation to the brakes is because it probably causes the front end to move up and down (or back and forth) as I start pressing down on the brake.
