Since its getting warmer out, I have my windows down alot and when I do I hear this scraping noise that sounds like its coming from the right side (don't know which wheel yet) The noise speeds up as I go faster. When I hit the brakes to stop the noise goes away. But then it's back when im accelerating. Also, if I hit a bump in the road the noise will go away for about 15-20 seconds. It also will get louder sometimes when I turn. I've been leaning towards the bearings but im just not sure with those conditions. Any opinions? Thank you.

 

Well this could be a few different problems, a sticking brake caliper or i have seen a dics brake pad gets stuck and start wearing funny because the steel brake hardware rusts up or gets so covered in brake dust and whetever , on mine i had the rear brake shields rust out so bad that pieces were rubbing on the rear rotor. and it could be a possible bad wheel bearing, but would be making a bad sound regardless of brake action, try jacking up each wheel and spinning it to isolate the problem, hope this helps.

I dont know if this changes anything or not, but the noise also doesnt start untill about 5-10 minutes into my drive after I use my brakes a few times
