Hopefully some of you can help me out, or give me an idea of possibilities. Lately my car has been making some sort of loud screeching/squealing noise when I'm driving. It doesn't happen when I brake. Just casually driving (freeway, streets, etc...). Comes and goes, usually on hot days and/or long drives. I believe the sound is coming from the passenger rear-side of the car. I thought it was possibly a wheel bearing, and had that replaced. Unfortunately, the sound is still there, and can get really loud at times...

Any ideas/experiences with this problem?

Try to pinpoint the location of the noise. For example, is it coming from the driver's side of the engine where the drive belts are located?

It's probably one of your belts

I think it's coming from the rear of the car, which has me thinking suspension. And no, I don't believe it to be a belt. This is a different kind of squealing noise.

Are you sure its not brakes? Rear disc? Sometimes the clips that help hold the pads can come loose and move into the rotor. You dont need to apply the brakes to have this sound happen. The pressure of the caliper can actually push the clip back into place, but over-time if its loose it may make its way back to contacting the rotor, thus long trips it may happen more often with less braking. I would suggest jacking the rear up and spinning the wheels by hand to verify

If its belts, does the sound change with engine rpm?

Yes, rear disc brakes. Hmm I shall check the brakes then.

Sound comes from the rear, so I still doubt it's a belt.
