Metal rubbing sound from my wheel?
Yesterday my car started making a metal rubbing, almost a screeching sound coming from my passenger side rear wheel. I can tell that it coincides with how fast my wheel is turning, as the rubbing gets quicker as the car does.
It sounds like metal on metal. I took the wheel off and inspected, and there was nothing obvious wrong in there. I removed the pads (Hawk Performance) to inspect them and they looked fine with no uneven wear. There is no horizontal or vertical movement in the wheel. It almost sounds like brake pads or something grinding into the rotor, so I'm going to pick up a dirt cheap set today and swap it out for a few minutes so I can rule them out. What else could it be? Wheel bearing? |

I'm thinking also maybe a stuck caliper. Is there any way to troubleshoot this?

Re: Metal rubbing sound from my wheel? (Tourney3p0)
if it ain't the pads... check the wheel bearing or u-joint.
the easiest way to check for a bad caliper is to grab the piston with big arse pair of channell locks and SQUEEZE! if nothing else, it will free up the piston. also, make sure the pins are clean and well lubed with anti-sieze!!! [Modified by bogus, 8:34 AM 1/6/2004] |

Still, I'm really not putting much hope in it being the brake pad since everything looked to be in great shape, visually. The only thing I can think of is one of the rocking retainer pieces on the outside brake pad was a little loose, so maybe I have some movement in there. I tightened it up and it didn't seem to help. |

Front or Rear?
If rear, check your parking brake. If front check your caliper, there may be a stone stuck between your pad and rotor, or check wheel bearing for play. |

A u-joint would be more of a tick....
Maybe your pads are just wore, is the sqeaker hitting the rotor?? Other then that I would vote wheel bearing. |

It sounds almost exactly like something scraping the rotor as it turns, but I'm not seeing any grooves in the rotor. The pads look almost brand new, and I don't see anything at all that would be touching the rotor in a normal, working setup. |
Re: Metal rubbing sound from my wheel? (Tourney3p0)
With the wheel and tire in place, raise the car. Movement by pushing and pulling at the 12 and 6 position would indicate a wheel bearing. Movement at the 9 and 3 positions indicates suspension issues.

I don't have any horizontal or vertical movement in the wheel. Could it still be a wheel bearing without any vertical movement?

Re: Metal rubbing sound from my wheel? (scorp508)
Could it still be a wheel bearing without any vertical movement? Generally no because when a wheel bearing goes the bearing has worn so that there is excessive clearence allowing the unit to rock in itself. I appreciate the help. I'll see what I can do and follow up when I figure it out. |
Re: Metal rubbing sound from my wheel? (Tourney3p0)
Did you try jacking it up & turning the wheel by hand?? It could be somthing even rubbing on the half shaft?? Like a disconnected e-brake line?? :smash:

Re: Metal rubbing sound from my wheel? (Tourney3p0)
I am doing wheel bearings on a 94 now and the sound I was getting was a grinding, much like the sound you get when you first apply the brakes on a rusty rotor. In my case I had about 3/16" movement at 6 and 12 o clock. Could something have lodged between the ABS sensor and the toothed rotor on the hub? Try removing the ABS sensor and see if anything falls out.
Just my 2 cents :leaving: |
Re: Metal rubbing sound from my wheel? (Trog)
Alright guys, I went home on my lunch break and changed my rear brake pads. The sound is still there so it's not that.
I verified that I have absolutely no movement between 12 and 6 or 3 and 9, or anywhere in between. It's solid as a rock. Good idea on the wheel sensor. I'll remove that when I get home and make sure it looks okay in there. Here's one thing I'm not sure about.. I had to use a c-clamp to push the piston in when I was changing the brake pads. There was normal resistence with the c-clamp, but after it was pushed in I could freely move the piston in and out of the caliper with my hand. This doesn't seem like it's right to me. Is this okay or might it indicate a bad caliper? [Modified by Tourney3p0, 12:49 PM 1/6/2004] |
Re: Metal rubbing sound from my wheel? (Tourney3p0)
thats normal... once you push the fluid out, any pressure that was holding the piston in place has been relieved.
I would also check the tires... duh... make sure you don't have any cord showing! I hate to suggest rear diff, tho... ick. |
Re: Metal rubbing sound from my wheel? (bogus)
I hate to suggest rear diff, tho... ick. How about a warped rotor? Again though, I'm not seeing any uneven wear on the rotor or the brake pad. [Modified by Tourney3p0, 5:39 PM 1/6/2004] |
Re: Metal rubbing sound from my wheel? (Tourney3p0)
I was able to jack up the rear end of the car and put it in neutral. It's not in my brakes at all. The sound is coming from the far end of the half shaft on the rear passenger's side.. I believe this is u-joints. I'll look to the archives and my Helms manual for further assistance.
Thanks guys. |
