Abs and Traction ctrl light on after replacing rear wheel hub!
I replaced the Left rear hub assembly and now the abs and trac lights are on, There is an abs sensor connection underneath the hub and closer to the diff, but it looks untouched. I tried to take the sensor out to see if it was dirty but after removing the 8mm bolt i could not get the sensor out as it is plastic and i thought i might break it. Anyone know how the sensor is supposed to come out?

Re: Abs and Traction ctrl light on after replacing rear...
The senser is most likly damaged but the area inwhich you removed the bolt is a thickened area you must take plyers or channel locks place them around the thickened area and easly move left to right once it starts to move continue left to right also start pulling upward this will remove your senser.(most likly the senser is broke on the inside ) you can also take it to your local auto parts store have them to put i on their computer it should tell you what senser is malfuctioning.hope this helps.

Had the same problem with my 2002 Lincoln LS, it was a bad wheel speed sensor. The right front wheel bearing had some play in it, so I had the hub assembly replaced. The hub assembly comes with a new wheel speed sensor attached. After I replaced the hub assmbly with sensor, the ABS and Traction Control lights went off. No problem since!
Hi, the wheel speed sensor and tone ring are built into the bearing/hub assembly. Make sure the new hub contains an ABS wheel sensor and the cable was properly connected. If it is properly connected, the new hub may be defective.
MAKE SURE TIRES ARE ALL THE SAME SIZE FIRST OF ALL,NEXT MAY HAVE A SPEED SENSOR NOT OPERATING PROPERLY OR BENT OR MISSING EXCITER RING ON FRONT HUB OR REAR AXLE. EITHER WAY THERE IS AN ABS FAULT OR A DIFFERENCE IN WHEELSPEED ON ONE OF THE FOUR WHEELS CAUSING TRAC LIGHT TO ILLUM. VEHICLE THINKS YOU ARE LOSING TRACTION AND APPLYING ABS AND MISFIRING VEHICLE TO SLOW DOWN UNTIL TRACTION IS RECOVERED
low trac light and abs light run hand in hand. first thing id check is the code stored in abs module. youll almost guaranteed to find a bad abs wheel sensor--which to replace is a wheel hub assembly ....hope that helped you out
One of your wheel speed sensors is not functioning and this is why you are having the abs and trac control light. These are on the back side of your wheel bearing hub assembly and you may have a broken wire or a damaged sensor. Check all four of these visually and with a continuity tester to find the bad one. The check engine light is usually emissions related and I would suggest replacing your O2 sensor.
your traction control works off of the abs unit did your abs light come on also? if there is a problem with the abs it will shut off the traction control. might wanna have the abs system scanned for trouble codes.it is also possible the conditions you were driving in caused erratic readings so if it has not come back on it is probably ok
