I have replaced both front wheel bearings about 10k miles ago under warranty at the VW dealership. But then about a month ago, I heard some bad wheel bearing noise again! I took it to the local reputable garage instead of taking it to dealership this time. They said the front left wheel bearing is gone bad, and the guy was suspecting that the mechanic in dealership probably didn't look at the hub when they were replacing the bearings last time, and the bad hub might have caused the bearing go bad again so quickly. So I replaced the hub assembly and the bearing again. The thing is, now I got my car back, but I still hear some noise very similar to the bad wheel bearings. It's not as loud as before, but it's still audible. What could be the problem? I hope it's not the bearing again!
I have an aftermarket suspension(neuspeed springs, koni shocks) and some performance upgrades(chip, exhaust, front mount IC). Could aftermarket parts like those cause problem like this over and over?
Best thing to do if you already changed the hub and bearing is to replace the assembly on that side, I have had, although rare instances where after replacing the hub and bearing the noise still persists. I would change the spindle assembly on that side and problem will be gone.

Believe it or not.. The aftermarket parts are better for YOUR CAR they are designed to improve your suspension. Take it back and ask the Manager or Mechanic to go for a ride. I do this all the time when I can't find a problem and instead of me thinking this guy is nuts, I let them drive and they say "HEAR THAT" then I know where to go. I would hate to guess but the dealership could have also just repacked the grease in the bearing to shut it up…. Did the other mechanic say if it was OEM part, it is easy to tell..

you could try your master cylinders and or the whole hub Assembly again ! r you sure its not just your rotors ? if they are worn or warped they could cause the rubbing /loud turning noise

Jin,
Let me start by saying I am a former Master Technician for BMW of North America. Next, let me tell you the first rule in automotive repair, new does NOT mean good parts. I can't begin to tell you how many times I've replaced "new" parts because they were defective. That being said, I would also like to say that anytime you alter the vehicle's factory settings "ride height, vehicle track" you run the risk of creating a new "problem" for yourself. If you have indeed altered the suspension then I would look very carefully at the track of the vehicle (do you know the caster, camber, and toe angles?) These are things that should be left to professionals. If you have altered any of these angles beyond the factory designed specs you may be getting road noise from the tires, but chances are that the wheel bearing noise was just "covering up" another noise, and now that the bearing has been fixed you can hear that noise. If it is a similar sound then I would immediately look at the tires and then move towards the drive shaft. You may find a mechanics stetoscope helpful in determining the location of the noise. Also don't rule out the engine pulleys!
