I have noticed on this forum their is debate over the sound of a rear wheel bearing thats failing.I have a high pitch squeel thats cycilcal and starts at around 30 mph,it will stop with a quick jerk of the wheel to the left.It is not brake related because braking will not affect the noise.I just changed the front bearings and am still hearing the noise.This leads me think its the rear bearings.I have read all the past threads on this subject and some people say bearings only growl when failing.My question is it possible that this high pitch squeel could be the bearing?

I had on fail on my 911. No squeal. It was a harmonic drone.

QUOTE(cary @ Jan 29 2011, 10:59 PM)  No squeal. It was a harmonic drone. (IMG:style_emoticons/default/agree.gif) It's usually a low pitch "grinding" noise, sometimes you can feel the vibration through the chassis. But i wouldn't discount the bearings completely in your case. They are cheap enough and they are a wear item. If you don't know the last time they were replaced, you might as well. For all you know, they could be 40 years old ... (IMG:style_emoticons/default/shades.gif) |
