I have a 96 sts and it makes a humming or buzzing or low roaring noise (hard to describe) while driving. With the steering neutral or left turns only. In partial throttle or decel it is most noticeable. The CV joints do click during turns. It is not noticeable truning the wheel while not moving. Also no codes. Any ideas?

Re: humming noise
Sounds like a right front wheel bearing. Does the sound come and go as you make a series of "S" turns like a NASCAR driver warming his tires?
