High squeal noise coming from rt front end. only when i drive over 25 mph. only forward not when driving backward. changed brakes. sound stops below 20mph. seems to be coming from underneath car...not in engine area. cannot hear when hood is raised. does not make noise when car is in park and engine is reved up to same rpms. which are about 2.5. only makes noise when actually driving car.

Sounds like a dragging brake pad. There is an adhesive that can be applied between the calipers and the pads. Or it may be time for a rear end brake change.

1.let car sit overnight. 2. Start engine, put A/C on high, let it idle for 20-25 minutes, 2, then drive car uninterrupted for 60mph for 10 minutes, 3. slow down to 25 mph for 4 minutes, come to a complete stop with foot on brake let it idle for 2 minutes, 4. drive again at 30 mph for 8 minutes, come to a complete stop let it idle with foot on brake for 3 minutes. 4. Drive at 40 mph (turn off overdrive) for 6 minutes. 5. Drive at 20mph for 3 minutes at a time, each time coming to a complete stop with foot on brake for 2 minutes. Do this 4 times. Let the car cool overnight and repeat entire process. Then check status of systems with a code scanner.

check frame and body mounts

inferior pads or improperly installed. it could be that they just need to conform to the disc and the sound will go away, but you should find out that everything else is ok. if you got one of those brake jobs with a lifetime warranty, then its definitely because of the pad material.

you need to check the front brake pads to see if the warning tab is touching the rotor ,this will squeal if the pads get worn out before it goes metal to metal, and if that is ok the only thing i would think of is the wheel bearing,

yes...your engine belt is little bit lose that's y its causing noise...and hope when u speed up..it will stop squealing ..right?? so just tight your engine belt little bit and it will solve your problem in a min...take care n have a safe journey...n also if it help...rate it plz

Wheel bearing !!

I had a similar problem. The dealer change automatic transmission and differential, but the noise continu. After research on internet i think the problem is the front galiper who create a vibration on the disc wheel and the vibration frequence follow the front axle until interior car. Just press slowly the brake pedal and if the noise stop , that's it the cause i think. I dont change my galiper, but i have a new transmission . :)))

Sounds like rust build up on the rotors,this is a common problem with after market rotors,or it is a squealer tab and they squeal to warn you before damage is done to the rotors when brake pads are 2/3 worn down.have a brake inspection done.

Maybe yall should check the power steering pump.Hubby said it could be that. Repost and let us know if and when yall get it fixed!
