I have a 2004 alero and when I press on the brakes to stop at a red light or stop sign a vibration occurs and it's loud but when I put it in park it stops vibrating. What can I do about this problem?

If your vehicle is equipped with one,you've most likely got a defective brake/stop light switch.It will cause the brake lights to stay on continuously,not come on at all or prevent the shifter from moving out of park.If this switch is bad,it can cause just one of the symptoms above to occur or all of the symptoms above.So in otherwords,the brake lights can still be working just fine,but it can still cause the "shifter is stuck in park" issue you're having.However if your brake lights aren't working correctly,that's definitely a sign the switch is bad.

yes, it will not fit other wise. the squealer should be placed on the out board side of teh calipar as this pad wears the quickest

It's your exhaust mounts or broken exhaust bolts. It does it in drive st idle n under load because the motor is sitting in rubber mounts made to dampen vibration. Therefore the motor tilts to the left in reverse pulling the exhaust away from your under carraige, and to the right in drive causing the loose exhaust to vibrate against something. Check your heat shields also. They fall apart n do the same noise. Piece of cake.

try and rotate the tires if on has a problem the vibration will change to the rear

Check the rear area of your truck and see if the tail pipe is near anything, since there is torque on the motor and drive system while you are stopped at a llight, or you can block the tires and put on e/r brake at home with truck in gear, then look and listen underneath truck to find source of rattle

Have your Motor Mounts and Tranny mounts checked.

My rio kia bought on from uyi technical dealer in benin city, edo state of nigeria only 4 months ago is vibrating with noise while driving. The noise is noticed by other road users even in motion, making a very loud noise or sound that is highly embarrassing. The dealer mechanics have checked more than twice yet no result, instead the hub bearing is observed; tyres are turn over yet the noise persists.

What do think is resolution to the problem? pls help me. Vinson- [email protected]

This car has regular shoes on the back not disc. Replace shoes and adjust cable. No parking brake is a sign of worn out shoes. Regals have rear disc on them for this year.

Hi Ali,

This sounds like one or more of your motor/powerplant mounts is broken. Here is an easy test:

Have someone sit in the driver's sear with engine running and trans. in Park.
You stand in front with the hood open. Have them shift from Park to Reverse, and then Drive and back to Reverse and Park, taking time to stay in each gear and give some throttle while holding the brake pedal tight. This will rock or move the engine a certain amount as they shift through the gears and apply power lightly. It will move alot more violently with broken mounts.

If you have a clunking noise on Reverse shifts, you should be able reproduce this with the hood up and pinpoint the noise and/or sight the faulty motor mount with a friend's help. Good luck, I hope this puts you on the right track to fixing this annoying noise.

Sincerely, Tater Todd

Maybe it's the transmission itself. check it.
