Traction control light keeps coming on, also ABS light and trac off light comes on. The service traction control will stay on about a minute then go off, the other two will stay on. Have changed the right front hub assembly three times and it still comes on. Any suggestions? Thank you for your help.

You need to get it scanned to see what codes are stored. There are multiple sensors and wiring items that could be at fault, not just one hub. Four wheel speed sensors, ABS module, traction control system, transmission speed sensors are just a few. Plus the wiring that connects them all.

Thanks Steve, they have scanned it three different times and it keeps telling them the hub is bad and it is on it is third new hub. I personally think it is in the wiring or could the brakes have anything to do with it? I just went to the store about an hour ago and it seemed to me that I had a brake grabbing, maybe the right front.

It is more than likely the wiring and not the hub. Not all that hard to test. You just unplug the sensor input at the ABS controller and check to see if there is continuity to the sensor end.
