Metal squealing noise after driving for a while

Need help! Stumped! I get a steady squealing noise after driving for about 20 minutes, then the squealing starts happening. If I hit the brakes, nothing changes. I cannot pinpoint the sound because while driving it sounds like it is coming from the middle of he car. As I slow down the squealing comes to a stop at about 5 mph. The only thing I can imagine it would be would be would be the brakes, but when applied nothing changes, then I thought maybe my calipers may not be moving freely and the heat with the ( still plenty of pad left ) old pads may be making noise. Thins has been going on for months and every time I take it to a shop they cannot reproduce! Mainly because it takes a while for the noise to start and no one will drive it long enough to reproduce the sound.

Manual trans? Check your TOB bearing and make sure it isn't riding on the pressure plate fingers.

Are you sure the transmission is full of fluid/grease?

Pop the hood when it is happening and see if it might be the belt tensioner idler pulley.

Make sure it's full of fluid and nothing is rubbing on the driveshaft.

That's a good idea. I had forgotten about that possibility. :good:
