Bearing, CV, Ball joints - I'm at a loss
 

Hey guys,

Had an issue a few days ago with pretty bad howling coming from the front end. Decided it had to be the bearing. After a replacement and a replacement of the replacement (new bearing was bad) the howling is still there but very faint and seems to disappear completely during a left had turn (replaced bearing was on the driver's side). Is there anything else that might cause the howling, CV axle, ball joints, or is it possible I have 2 bad bearings from 2 different resellers?
