High pitch squeal!!!
I have a '99 Jeep Wrangler TJ. 4 cyl automatic. For the last month I've had this annoying very high pitch squeal coming for the engine area. I have yet to find the source. If the engine is cold or warmed up it still happens. The times it goes away is every time I'm driving along and give it gas. Once I take my foot off the gas the squeal comes back. The more gas I give it, the more the squeal starts to fade until its gone. Even if i'm stopped at a red light or parked at idle, the noise is there. Today I tried to pinpoint where its coming from but I'm not too sure. I thought possibly a pulley or the belt, but it doesn't sound like its coming from there. After 5 minutes parked at idle the squeal went away. ANY info anyone has as to what it could be PLEASE post. Thanks!
Drop the belt and check alll pulley, alt, and power sterring pump. Under a load it is getting enough pressure to go away but when the load is removed it squeels. 5 minutes idling it goes away maybe the Alternator bearings.

I have a 95 YJ and I had a similar problem. I had a squeal and I replaced the belt, pullies, alternator and power steering pump. At first the squeal went away when the engine was warm and later only when accelerating. One guy on the forum said to look for an exhaust leak and I found that a bolt was missing on the exhaust manifold. I have not had any squealing after replacing that bolt.
I have this same issue. It only happens at highway speeds though. I can change the pitch of the noise with more or less pressure on the gas pedal. It sounds like my jeep is screaming at me. Or I just made a pot of tea. But I can't find where it's coming from because when I slow down it goes away. Lemme know if ya find your problem.
