Took our truck in to the GMC dealer today to have the brakes checked out. I had noticed that when applying the brakes at speeds between 5-10mph I could feel the ABS kick on. After combing the internet I had found that there is an ABS sensor in the wheel hub which is also call the wheel speed sensor and I guess they are known for going bad. You can purchase just the sensor for around $50. Which I didn’t think seem to bad. The GMC dealer called and confirmed what I had thought but also informed me that the entire wheel hub assembly needed to replaced and they won’t replace just sensor itself. I have read forums about pros and cons of replacing just the sensor and replacing the entire hub assembly. The dealers quote was around $750 per side. This seems very high. Monday I will call around to see if I can get a few more quotes. Hoping for a better price. If anyone else has had this problem I would love to know what you did. Did you replace just the sensor or replace the entire wheel hub and what was the cost?
