Strange noise

[machlang]

Hi!
My 2007 Corolla makes a humming, vibrating noise when I am going straight or turning right. The noise totally disappears when I make a left turn. Is it likely the wheel bearings? I have looked at the CV boots and none are torn.
If it is the wheel bearings does the spindle come off by turning counter clockwise and does it take a 33mm socket?

Thanks in advance for your reply.

Sounds like the front left wheel bearing. I think it's 30mm, and that you can use a 1-3/16" socket. Both right and left spindle nuts are loosened counterclockwise. Steering knuckle has to be removed from axle, strut, ball joint, and tie-rod end to have bearing pressed.

Here is the best way to know if its the wheel bearing (which I'm 99% sure it is).

Jack the car up on jack stands(preferably 4 wheels but at least the front wheels on a LEVEL SURFACE)

With the car in the air start the car and put the car in gear. Both wheels should be turning at this point.

While the wheels are turning reach your hand in and grab the coil spring on the strut. Grab it tight and feel the spring.

If the bearing is good the spring should have no vibrations going through it and should feel smooth even with the wheel turning.

If the bearing has failed the spring will feel harsh as if something is grinding and resonating through the spring.

You can do this on all 4 wheels. With the rear wheels simply spin the wheel by hand and feel the spring.

I have used this on every single wheel bearing complaint I have ever had and I have never had a comeback. It has been a 100% effective way of determining bad bearings.
