I have a humming from my front end...both hubs have been replaced. When I turn the wheel slightly (going around a curve) the humming stops until I straighten out once more. It only stops humming when the wheel is turned to the right.

Any idea whats going on?

Thanks

 

A humming or a whine?...
Id start with checking the power steering fluid... Does the sound speed up if you raise the engine idle in park?

When you did the hubs....Did you replace all the bearings?
