I was spinning tire for about 45 seconds before the noise.

I've recently did the brakes and rotors, noise came before that. Didn't get any better or worse after. I've checked for rubbing, but I don't really know what I'm looking for. This is the first car I've had, that I've done the work myself, I'm still pretty new to it! Could this be causing it ...

Did that.

Hey everyone! I have an 06 XC90 2.5T 186,000. I can not figure out where this noise is coming from! It's from drivers side, rear wheel.

How do I make a new post? Need help figuring out noise from rear drivers side.
