Be a real bad day. If its real bad it will lock up, and you don't want that at any speed. I have a nice "How to" on here showing how to check and change wheel bearings

But they can be noisy a long time before they seize up. If you have ABS and the light hasn't come on yet you're probably good for a while yet. But one day the reluctor sprocket will lose it's alignement with detector and ABS light will come on, then you kinda have to change it. When the noise get's to annoying and you have the cash get it changed. My tolerance for bearing noise is not very high and I usually change it early.

Well I used the term sprocket as an adjective because I thought it better described the toothed reluctor ring, but GM calls it a reluctor even to this day in their service manual. The term started way back when GM introduced electronic ignition in their distributors to replace the old point system. It had a reluctor ring to ignite the spark at the right time. Here is what it looks like for those who don't know what a reluctor ring is. It's that sprocket thing a-ma-gigy on the back of the bearing.

No no... dont take it wrong way...i think it is funny how terminology can be so different...you know...bonnet---> hood....stuff like that especially when were working on the same items. I guess I use excitor ring because the peaks excite the sensor to react..in same sense does reluctor create resistance and that is why it is called reluctor sprocket?? just wondering buddy ..no intention of insult coby...when you said reluctor sprocket I was thinking "what the hell is that" when I reliezed what it was it made me laugh. :]

Just a picture I got of google. It is called a reluctor ring because of the reactance it produces with it's ajoining inductive coil pick-up. Since a coil cannot produce a square wave it produces a spike at each edge of the toothed ring. One spike is positive and the other is negative. The circuit eliminates the negative spike and clips and amplifies the positive spike. This circuit counts the number of spikes per second therefore knowing the velocity of the wheel which it can compare to the three other wheels. Coming back to the thread topic when a bearing gets bad enough this reluctor ring misaligns itself with the pickup and no more pulses are produced. Circuit detects one wheel is stopped and three are turning and puts out an alarm. In this case it disables the ABS pump and turns on the ABS light.

U know krjrcustom1, that is my big problem with writing. It is hard to put in words ones tone of voice. Emoticons help express the tone better sometimes . I'm not easily upset. But I often misunderstand peoples intentions. Plus english being my second language sometimes I just plain don't understand.
