I noticed a new noise (one of several) on the 2005 Impreza Outback Sport, automatic transmission, 254K miles,  that we purchased back in June. This one showed up a few weeks after buying it. It's an intermittent rattling, grinding noise, I believe coming from the front end. It doesn't appear to be speed dependent, but it most audible at low speeds around 25- 30 MPH. It also goes away when the brakes are fully applied which leads me to think it's brake or drivetrain related. You mostly can just hear it but can feel a little something through the floorboard as well.Feels like a deeper noise than the typical exhaust shield rattle.

This appeared after new brake rotors and pads were installed and I believe before both front axles were replaced (with no change). I plan to go in and recheck that the brake calipers are tight, but also wonder if it is a front differential issue possibly.It doesn't act any differently on turns, so not thinking wheel bearing, but maybe.

Here is a link to an audio clip I made where you can just barely make out the noise.

I think I hear a clunking noise. Caliper guide pins. Our 95 does it on dirt roads. Touch the brakes and the noise stops.

maybe a dust shield is loose?
