I was driving to work today and I notice that every time I pass another vehicle, I hear a high pitched noise (squeal?) from the front left of the vehicle that can best be described as one quickly rotating piece of metal scraping against another piece of metal. I roll my window down and I can just make out the noise as Im cruising (40mph) down the road. Every now and then it would go away, but it was there pretty consistently. The tone sounded fairly constant also; it only changed tone as I sped up or slowed down, and it didnt change much at that. While I could barely hear it while driving, the noise must have been quite loud from outside the car because it sounded pretty loud every time i passed another vehicle and the sound waves were reflected. Eventually, caution got to me, and i pulled over about a mile and a half from where I first started hearing the noise. While I waited for my ride to come pick me up, i popped the hood and put the car into neutral, and revved the engine to build up a little boost. doing this, i never managed to recreate the sound, even though I know the turbo was spinning.
I havnt been back to look at it because I had to get to work, but does this sound like a dying turbo? Thats the worst case scenario, i think. The only other things I could think of is maybe a brake pad, or something to do with the axle since it was recently replaced; after that Im all out of ideas on what could be causing this. Any help on this one?
