Car emitting a constant squeaking sound...?
I have a 2004 Ford Freestar minivan. When I hit about 35 MPH, the car emits a constant, high pitch sqeaking sound. The sound reminds me of a brake scraper grinding on the rotor. I replaced the brake pads all the way around (disk brakes on all 4 wheels) about 2 years ago with Raybestous Ceramic pads. To the best of my recollection, there were no scrapers on any of the pads.
I pulled off all the wheels today and the brake pads are still 50% to 75%. The wear on the pads seems even and I don't see any signs of caliper issues (leaks, hung calipers, etc...).
The pitch of the squeak is not change when the brakes are applied. The squeak will go away briefly when the weight of the vehicle shifts from side to side like when I turn. If I put the car in neutral when I am moving to disengage the transmission the squeak is still there.
I am a bit at a loss. I haven't heard a bearing make that high pitched squeal before (though I am only a home mechanic, so the fact I haven't seen it doesn't mean much). I'm not sure if it is the brakes as the pitch of the noise doesn't change with applying the brakes.
Any ideas on what might be causing this?
I didn't think about checking the CV joints because I thought they usually clicked not squealed. However, I did notice a few times that there was a real acrid burning smell that didn't smell like any burning auto fluids that I was aware of. It almost smelled like burning rubber.
If the boot split and started throwing grease everywhere, that might explain the smell. I'll have to jack it back up and check.
