Thread: 4 Wheel Drive

  1. #1

    Exclamation 4 Wheel Drive

    My 01 Suburban isn't going into 4 wheel drive. It engages but the front tires won't lock. I have replaced the actuator and the switch on the dash. If anyone could help me soon it would be very appreciated. We just got snow here and the burb won't go up little baby hills.

    Are you talking about the parts in the front passenger axle?

    If you replaced the switch and the actuator, then chances are that you have an encoder motor issue.

    Thanks for the help guys but I needed to rebuild the front diff. The washer type thing in the diff got pushed around and screwed everything up.
