Hi folks, I'm back. So, I ordered a couple of AC Delco sensors from Rock Auto. It is the left front that is acting up most, if not all, the time. When coming to a stop MOST of the time it activates, the steering wheel will roll to the right just a bit indicating the left brake has released. The fellow who is doing it for me was willing to pull it, sand the rust off the hub clean the sensor and put it back in. I figured I'd better have a replacement on hand in case the original breaks when getting pulled out.
After thinking about it, and discovering that the left and right are not interchangeable, I ordered both. Since I have to pay for the labour at this time (still a gimp) I think I will just get him to put in the two new ones and be done with it. I'll clean up the ones that come out (if still in one piece) and keep them for spares. He can plug in his scan tool to see which one is failing, but I'm still thinking to replace both anyway.
About the hub assemblies, good ones were going to be $200+ each by the time I got them here. The sensors are $50 each shipped.
Cheers,
Glenn
