I ll get right to the point. Ive recently replaced the pads and rotors, which kept the amigos away for well over a month. Today i started the truck to go to work they came on before i even moved an inch. Im pretty sure its the front passenger wheel speed sensor, and i need to know how difficult it is to change. Also this is my first awd vehicle, does this affect that. I contacted atlantic british abou the price of one but havent gotten a response yet. Any ideas or suggestions, or any input at all is appreciated. Thanks in advance everyone. I probably would of sold this truck by now if it wasn t for the help i get from this forum.
