THIS TRUCK IS A MISBUILD FROM THE FACTORY ON THE BRAKE SYSTEM PLUMBING. I AM CONCERNED OTHER UNITS MAY ALSO HAVE BEEN BUILT WRONG. THE TRACTION CONTROL LOCKS UP THE FRONT DRIVE AXLE BRAKES WHEN THE TRUCK SPINS A TIRE AND KILLS THE ENGINE CAUSING DAMAGE TO THE DIFFERENTIAL AND LOSS OF CONTROL OF THE VEHICLE. I HAVE IDENTIFIED THAT THE SERVICE BRAKE AIR LINES ARE HOOKED UP INCORRECTLY FROM THE FACTORY, NOT GOING THROUGH THE ABS MODULATOR VALVE. THIS ALLOWS FULL BRAKE APPLICATION TO THE FRONT DRIVE AXLE SERVICE BRAKES WHEN THE TRACTION C…
