View Full Version : Does a failing wheel bearing sound like a chirp?

I am getting an intermittent chirping noise that changes in frequency with the speed. It is coming from my right rear wheel. I took the wheel off and when I turn the hub, I can hear a faint noise. It seems to be once with every revolution, but it is so faint when I do this I may be missing some.

Could this be the early stages of a failing bearing? Do you think it would be safe to drive the car, or should I dry dock it until I can get the problem resolved?

Thanks,

but the pace at which the sound occurs. I can only hear it when driving in town, but the tone of the sound does not seem to change much, if at all.

does it happen when power is applied, or when its off, or all of the time? i think one of my cv joints is dry because it will groan a little at certain speeds, as well as FULL lock turns in the direction of the suspect unit. if its all the time/power off, its probably a wheel bearing, power on--cv joint. can you introduce "play" into the wheel with it off the ground?

that it is drowned out by traffice noise, etc. much of the time. However, I have tried coasting when I hear the sound and the sound is still there. Even when I apply brake pressure, the sound is there.

I haven't tried to see if I can introduce any play into the wheel.

Thanks for the suggestion.

seen one fail bad yet though...so I wouldn't get too concerned about not driving it. I don't think i would go on any 130 mph blasts on the highway though but for normal driving i wouldn't worry that much.. Check the wheel for play when you have it up in the air, grab the top and bottom of the tire and push-pull to see how loose the bearing is.. I had one on a front wheel drive nissan last week that I could move almost 2 inches and the driver hadn't noticed anything except the tires were wearing extremely rapidly on the edges from the tire fluttering around...:)

I am not certain that I can even get my 525i up to 130 mph anymore. Although I haven't tried it since I put on the Throwing Stars I bought from Micah. They certainly look fast, so maybe........
