I've been noticing 2 things lately. When I go to work, I've got a couple windy roads before the freeway, and when I stop at a light after a couple windy turns I notice a sort of rattling and grinding coming from the back, I don't know if it's just the spare tire in the trunk may have gotten shifted around so it's rattling, but if I put it in Neutral and hold the brake it quiets down, then when I put it back in drive and hold the brake it gets louder.

Also, I've noticed when I make corners I get a kind of squeaky grinding sound in the front, more squeak then anything. Is that just from age or is it wheel bearings? The front stabilizer bar was replaced not too long ago since I cracked it just before the bushings on the passenger side back in February-ish on some rough road.

 

I'm taking a guess one of two items:
- The warning tabs on your brakes are hitting
- Wheel bearing

I lean on brake pads going out. I've had some pads in the early phases of being worn out, the tabs only made contact sounds when turning. Best thing to do, start popping the wheels off and take a peak at the tabs and how close they are to the rotors.
