You hear a high-pitched squeal that stops when you shut off your engine: Readjust or replace the belt. These belts should have about half an inch of play and ...Missing: 1999 plymouth breeze
Sounds as if you may have a vacuum leak. Use a length of hose with one end in your ear and the other move around under hood to help locate the sound. BE CAREFUL TO AVOID SPINNING FAN AND OTHER OBJECTS. I ASSUME NO RESPONSIBILITY FOR THIS PROCEDURE.
To address your first problem squeaking brakes aka "brake squeal", is most often casued by one or 2 things: "Pad vibration" or a "low brake warning sensor".
Pad vibation is usually caused by ineffective pad anti-rattling clips & hardware that allow the pads to vibrate at a super fast speed whenever the brakes are applied, thus causing a high pitch brake squeal. To correct this, replace all the pad hardware and anti-rattling clips and make sure you use a quality pad set that has anti-rattling plates attached to the backs of them. Weather conditions do affect brake squeal, that is why it seems to be worse at times.
Low brake warning sensor squeal occurs when your brake pads reach the point of replacement, the sensor attached to the pads scrapes on the rotor which produces a high pitch squealing sound to warn you it's time for new pads.
As far as your second problem goes (a knocking sound), I'll need more information about the problem before I can offer a possible cause (eg. happens on left or right turns, while going over bumps, at high or low speeds, accellerating...).
I'd check the passenger side mirror first, make sure it is tight to the window frame, no gaps. It causes a wind noise or whistle. It could be from the outside of the truck, try to pin point. Does noise go away with either window down? Does noise get louder turning in one direction (wheel bearing)? Does it get worse then seem better (could be tire noise)? Eliminate fan motor, and radio. Does it get worse with vehicle speed or just engine speed?
Mine has a high pitched whistle at high rpms and I can't figure it out. But mines def not the tranny. I'm thinking it's a vacuum line somewhere. It's a 97 2.3l manual. The colder it is the louder...
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.
Vacume line off of transmission won't alow high gear and at that speed the tranny starts screaming for relief. Find the vucume line and make sure its good and connected at both ends
