Humming noise from driver rear wheel on 09 camry

if hub bearing replacement did not fix the noise

when noises are on left and right turns
that has CV joints /drive shafts
would say they are the issue
replace both sides

and replace the left hand hub bearing at the same time

Sounds like you replaced the front bearing. Could be a rear wheel bearing, or one of the tires.

bad wheel bearing/ faulty brakes

Sounds like a wheel bearing. Jack up front end and spin wheels by hand and listen for grind. Same for rear wheels. Make sure brake linings are good all around. Do the swerve test. Drive down road bout 40mph and swerve moderately one side to other. If noise gets louder with weight shifted to one side more than other its most likely a wheel bearing.

most likely if its a hum it could be tires , if its a roar it could be the drive train

support the vehicle on jack stands , start the engine , put in drive and let it idle, if noise is gone ...its the tires if not check the drive train ...start with fluid levels

sounds like the wheels are out of balance, is there a slight vibration through the steering wheel at this speed? and does the problem stop if you go faster (please drive carefully)

does it get louder above 45-60mph? and much quieter at low speeds. It could be wheel bearings, a rear differential or front differential. If its a grinding humming noise its wheel bearings, listenin to see if theyre coming from the front or rear, left or right, or both when your driving to know what wheel bearing are bad. If its a whinning noise, its probably a differential. check and listen to hear if its coming from the front or rear. Also, check for loose plastic around the wheels. Lastly check your tires for uneven or choppy wear. move your hands front to back on the top of the tire. does it feel really choppy and rough, maybe you just need new tires

Noises from axles can be really deceiving. The sound is transfered throuh the transaxle and can resonate through the entire vehicle. The turning to the left thing makes it sound like a problem in the right wheel/axle area. Wheel bearings and axles tend to make worse noise when they are on the OUTSIDE of the turn. More of the vehicle weight is shifted to the outside due to centrifugal force. Thus, if the noise is louder when turning left, this puts the right axle to the outside of the turn and the most likely to be the source of the noise. (and vise-versa) The fact that the noise calms down while cruising makes me believe that it is not a wheel bearing. Wheel bearings can make more noise in turns, however, they usually make a "roaring" or loud "humming" noise that gets louder with speed. An axle is more likely to change or get louder according to engine load more than rotational speed. (Way worse while accelerating or climbing a hill) I would be taking a hard look at the right axle.

Sounds like the rear end itself, most likely if u have high mileage.

It sounds like a possible wheel bearing failure.Get it checked at a local repair shop ,or possible loose bearing hub.
