I have a humming noise when I get up to about 20 miles an hour while I'm going straight it feels like it's coming from driver side wheel but if I slightly turn the wheel to the left while going straight the noise goes away but if I hold the wheel straight the humming noise continues. And going around left turns it has no noise but going around right turns in hums. And I can also feel the humming with my feet on the floorboard.

Hi,

The left front wheel bearing is bad. When you turn left, the weight distribution is changed and more weight goes to the right side of the vehicle, lessening the weight on the left front bearing. That is why the noise stops or gets less intense.

If you look below, I attached the directions specific to your vehicle for replacing the front hub bearing. It isn't too difficult of a job but will require a little work.

If you plan to do this, make sure the axle nut and hub nuts are torqued to the specifications in the attachments.

Let me know if this helps or if you have other questions.

Take care,

joe

See pics below. Note in pic 6 I circled the component being replaced.
