2003 Corolla Humming

My 2003 Corolla has developed a low-pitched hum which seems be coming from the rear. It is definitely speed-dependent and is most noticeable above 50 mph. Origiaally thought it was tire noise from my snow tires but the sound has continued with the change to my all-seasons. Is it likely to be a bearing? When the bearings went on my Jetta they really growled a lot and you could determine the side by turning both ways and seeing which way the noise was worse. Any suggestions?

I have the same problem and it turned out the rear wheel bearing wad the culprit. Not a cheap fix (around 300.00) since you have to replace the whole assy.

The discount places sell the hub for about $115. & tax. any shade tree mechanic can install in 30 minutes. jackup the car. spin wheels sometime you can hear the problem. if not,then remove hub and spin by hand. the hub is interchangable. both of mine were bad.

Humming sound coming from rear of car when driving

Only when moving? Does pitch change with speed of vehicle?
Generally a humming sound from rear is a fuel pump warning you that it is getting near the end of its service life. You usually notice that more, however, when the car sitting still running and you walk around the rear of the car.
Wheel bearings can make a variety of different sounds, mostly noticed in the first half mile of driving. A "whomp whomp whomp" pulsing sound is the most definitive wheel bearing sound.
Slotted or drilled brake rotors can make a humming sound, but I doubt anyone put those on a '94 5 Series. Worn tires can get pretty noisy, but you would have figured that out if it were the problem.

I have a humming noise coming from the rear at 55 mph. Road surface doesn't affect it. It isn't there at slower or faster speeds.

Your rear wheel bearing(s) need to be replaced.

This sound is a humming that will go with the speed of the Chassis, not the speed of the motor.

You will hear the loudest hummmm at around 55mph, as that speed is where the most vibration is created by the friction in the hub/bearing/wheel.

Bearings are not too much, but they usually need to be pressed in, so find a good shop to help. :)

Medium humming noise when backing up at low speeds

Probably rear brakes. Clean them up or get them looked at and try again.

I get a grinding noise and slight vibrations that I can feel under my feet. This usually happens at low speeds, but has become more noticeable now at c. 30 mph.

You need wheel bearings.. One for sure maybe 2. Do you feel it in the steering wheel or floor? The floor usually means rear and the steering wheel usually means front. Hope this helps. It should change pitch when you drive left to right at a steady speed. :-) Cobra

There is a loud humming from passenger side . at it's loudest at 50 mph, noticed the same time i replaced passenger side tire. any thoughts?

It needs a wheel bearing. You should notice that the pitch of the noise changes as you change the speed of the car. Also the noise is changes when you brake and/or turn, it may even disappear all together.
