wheezing screeching type sound

[mtpathy]

So all of a suddent my 94 SEV6 is making a noise up front, kind of sounds like a bearing dying. could it be a fan clutch or something. it sure sounds like it is a pulley bearing going bad, sort of screaching and going round and round.

 

I remember replacing the fan clutch on an 89 pathy a while back. is this maybe the same thing?

 

What do you guys think, i have not really checked it out yet, just rolled in from work and heard it just now. I will get a long screwdriver and listen to my bearings tomorrow, but i was wondering about ideas.

 

The truck is a 5 spd, with AC ,and has 320,000 miles, runs like a top.

 

Thanks

It sounds like your idler pulley to me.

does it mostly happen when you've been driving for a while? because I would get a high pitched squealing sound and at first i thought it was my brakes but there still good, so I checked my fan clutch and it was starting to pivot so i replaced it with a new one today I hope that was the problem lol.

As 94LE-BlackEmerald said, sounds like the Idler pulley bearing.

I am leaning to the idler pulley at this point, sounds like a bad bearing. we shall see
