The noise you are hearing may be caused by a loose or worn serpentine belt and is slipping during all engine speeds while under load. It could also be a worn serpentine idler pulley that has worn out. These are just two areas for you to consider,but it is hard for me to tell without actually hearing the noise. Take the vehicle to an autoparts store and have someone check these engine components for a possible cause. They won't charge you anything.

High pitch noise when excelarating past 75-80 mph, seems to be coming from where the dash meets the windshield. Becomes louder and more frequent when driving in really winding conditions. it goes away when...


Well how short a drive is it.........to get you to go nuts. Is it a high pitched whine? If so look to your right. Is the wife sitting there? If so. That's the problem. Going 75-80 in a 25mph school zone will cause that. And where is the speed limit 75-80 anyway.


It's the radio, btw, install an inline filter to filter out the alternator noise.

Whining noise when turning left seems to go away after vehicle warms up. limited quadra trac


Does the whining sound like it's coming from the power steering? This usually is an indication that the power steering fluid level is low.

Loud whistling noise while driving.


I think there is a TSB on that problem. If the wind is coming from the passanger side then roll the window all the way down. Put a 2X4 in the door jam. So the 2X4 will be inbetween the the door and the jeep. Push on the top of the door like you are trying to close the door. What you are trying to do and slightly bend the top of the door toward the jeep. But just do it a little at a time.
