Speed sensor how-to?

[Porda]

I've had my VSC trac and TSC off lights on since I bought my T4R a month ago. After reading some of the posts on this site I decided to take it to a friends to do a zero point calibration with his OBD-II code reader. He reset the codes, but the lights would not go away. We finally deduced that my front left wheel speed sensor is all sorts of f***ed up. I'm new to 4runners so I dont know where I would find the speed sensor (is it internal to the hub?) or how easy it is to replace. If anyone could give me some advice that it would be much appreciated :thumb3:

Did your vehicle have any suspension work? The speed sensors seem to be very reliable. The wire leading to it very fragile and more than one has been damaged during a shock change.

I replaced the front tie rod ends and ball joints. although the lights where on before that:wtf:. The previous owner might have had some work done on it that could have thrown the sensor off.
