  Q: How to replace the front wheel speed sensor on a 4WD on GMC Envoy?

  A:

  Before you start replacing the front Wheel Speed Sensor on a four-wheel-drive vehicle you need to remove the front Wheel Bearing and hub assembly. Remember to locate the Wheel Speed Sensor harness between the widest section of the bolt holes at this part. Apply white colored paint at the wheel sensor connector position on the wheel assembly. Focus your force on the Wheel Hub when removing the Wheel Speed Sensor without touching its tone wheel. Put the Wheel Speed Sensor in waste and use a proper device to pull it away from the Wheel Hub/bearing housing. Before installing set the Wheel Speed Sensor harness directly on the centerline of Wheel Hub/bearing assembly at the space between bolt holes. Push the new Wheel Speed Sensor directly onto the hub/bearing assembly until it sits securely against the housing wall. Put back the front Wheel Bearing and hub assembly with the speed sensor harness placed in an upward direction. Complete the assembly by attaching the Wheel Speed Sensor harness bracket bolt and fitting it with a torque of 20 nm (14 lb ft).

  Q: How to replace the rear wheel speed sensor on GMC Envoy?

  A:

  Before working on the wheel speed sensor you must lift the vehicle up. Unplug the wiring harness before you unscrew and take out the wheel speed sensor retaining bolt and sensor from its mounting place. You must clean both the sensor as well as its boss before installation. Put a tiny amount of axle lube inside the sensor boss hole to smooth the seal movement. Press the wheel speed sensor evenly into place until it sits flat against the sensor boss surface. Press the wheel speed sensor into bolt hole place then fasten the wheel speed sensor retaining bolt at 13 N.m with 115 lb in torque. Plug in the sensor electrical connector and let the vehicle return to the ground. Start the engine and let it run with idle speed to test if the ABS and traction control indicators stay lit. Drive the vehicle only when repair diagnoses are complete because damaged and improperly connected wheel speed sensors require professional service. Run tests to find the problem when the lamp lighting up persists. Choose a road that feels flat and clean with no traffic and only basic items standing in the path to drive the vehicle at 16 km/h or above for 5 seconds straight. After stopping analyze if either the ABS indicator or traction assist indicator lights up at night; take your car to its basic ABS diagnostic.
