sanford7575 Posted March 23, 2006 Share Posted March 23, 2006 I have a '91 Pathfinder with 109,000 miles, and I have a noticeable high pitched squeel coming from my front wheels. I changed the brakes and rotors about a year ago and I don't think that's the culprit. Also, the squeel doesn't go away by applying the brakes. What are the signs that the wheel bearings are going? At what mileage do they normally require service? Link to comment Share on other sites More sharing options...
94extreme Posted March 23, 2006 Share Posted March 23, 2006 grinding more the squeel but never know. check them to make sure. check the pads also.. there is a very recent topic on bad(?) pads. Link to comment Share on other sites More sharing options...
mws Posted March 24, 2006 Share Posted March 24, 2006 (edited) If the sound doesn't change when you use the brakes, it is most likely not the rotors or pads. Both wheels, or just one? If just one, the temperature test can help. Drive around then CAREFULLY feel the temperature of the hubs. Obviously, an infrared thermometer is best, but hey, keep in mind it could be 300+ degrees and use appropriate care and you should be able to avoid the burn ward. If the squealer is noticeably warmer, then the bearings are very suspect. Mileage? Somewhere between 500 and 500,000 miles, depends on: - "Robustness" of bearing (overstressed versus heck for stout) - Quality of bearing (roundness, hardness, surface finish, etc) - Quality of grease - How well they seal out water and dirt - How well they were assembled and preloaded British cars in the early 50's? On the low end. BMW's? I've heard of some with over 1 million miles... Edited March 24, 2006 by mws Link to comment Share on other sites More sharing options...
