If same tires as before & air pressure set correctly, or as usual, a humming when swerving, or turning one way or the other or both, it's usually a pretty good indicator.

    Just had this issue resolved on my 03 mountaineer; thought it was the differential making noise while turning. It was one of the front wheel bearings. Cost me 370.00 but the noise is gone.

When driving a 1990 300E, the front wheels shake when applying the brakes, Brake pads have at least 70% remaining. Alignment was good when last checked.


Most likely problem is brake rotors warped. If you replaced pads without machining rotors, or if rotors are getting worn and close to minimum thickness, warping is more likely. If you replace the rotors, replace the pads at the same time. The pads that are on the car now are wearing unevenly due to the warped rotors and can cause new problems for the new ones.

Uneven brake pad wear


usually if you hit a puddle of water, it will warp your rotor. you can take your rotors to a mechanic that has a rotor turning machine, and they can smooth them back to normal. thats probably why you are having uneven wear on your brake pads.

When i press my brakes my wheel shakes, what is this problem?


The brake rotors are warped. This is a common occurrence. It can be caused by numerous things; excessive rotor wear (too thin), uneven brake pad wear, sticky brake calipers, riding the brake pedal causing excessive heat buildup in the rotors, and over-torque of lug nuts are just a few causes. Having the rotors checked and re-machined may help, but normally they require replacement. If you replace rotors, it is advisable to replace the brake pads at the same time to avoid a poor wear pattern.

Front right tire makes a grinding noise , hub assembly has been replace problem stills there, what will be the problem?


It could be a lemon replacement hub or it could actually be the tire. Check the tires tread for irregular wear patterns. If the hub was loose prior to change this could easily cause the tire to wear in a "choppy" fashion which can also cause a rough humming sound that I have often heard customers refer to as a grinding sound.

I am trying to replace my brakes, and need to know if I should buff my rotars. How can I tell if I need to?


The brake rotors should only be machined (buffed) if they are warped, rust pitted or grooved. The thinner they are the less effective the braking.

2001 olds alero, When I step on the breaks it


Did you also replace the brake pads? If not, the wear from the warped rotors most likely caused uneven wear on the pads (not visible by looking at them, but apparent when you apply the brakes). This is probably causing it feel like the rotors are still warped. I don't believe your anti-lock brakes have anything to do with this.

The problem is more than likely the result of your front rotors being warped. You should either have them checked for this condition. Also clean and lubricate the caliper slides which will enable the caliper to move freely upon application of the brakes. use only silicone based brake part lubricant. Any oil based lubricant will cause seals and rubber parts to fail. I would change the rotors and pads.
