I have some weird scraping/rubbing noise in my right front wheel. I I hear it regardless of weather i brake or not, and the slower i go the more low pitched and grindy it sounds. It continues to scrape at normal driving speeds, but is very high pitched and not very noticeable. I do not hear it as much while in reverse.

what I have checked/tried.

  1. brakes look ok, the caliper must be sliding properly since there is even wear on both inside and outer pads.

  2. rotor looked pretty good but possibly warped.

  3. I replaced the front brakes and rotors, but am still hearing the noise

  4. It occours less when I am in reverse, or when Im turning right. It is more apparent while turning left, but it is happening all of the time.

so at this point I think it might be a wheel hub bearing, but it's not 'wubwubwub' noise everyone describes it as.

Here's the noise: https://www.youtube.com/watch?v=pN30O-m8CpY

    Does the car have disk brakes all the way around? It sounds like one of two things: either a drum on the rear of a vehicle (experienced the same sound on my truck), or it could be a dust cover on the disks brakes on the front. – Pᴀᴜʟsᴛᴇʀ2 Mar 23 '15 at 0:15
  • It does not appear to be the dust cover, i will double check that, and it is disc brakes all around. – MutantTurkey Mar 23 '15 at 0:19

    Could it be the wheel bearing? – MutantTurkey Mar 23 '15 at 14:48

It definitely does sound like a bad wheel hub bearing. Classic pattern of woob-woob-woob-woob. The sound is made as the bearing inner race wobbles around the outer race. This is a safety issue. Replace as soon as possible.

Did you take a look at the CV joints? A bad CV boot could have damaged the bearing by filling it up with gunk (a mix of dirt and grease). Like liquid sandpaper...

  • Confirmed wheel bearing. Front right replaced. Hub and bearing both were shot. – MutantTurkey Dec 18 '15 at 18:52
