  2. Measure the distance "B" between the surface where the front axle housing meets the ABS wheel speed sensor, and the tone wheel.
    NOTE: Measure so that the gauge touches the apex of the tone wheel teeth.

  3. Find the gap between the ABS wheel speed sensor pole face and the surface of the tone wheel teeth by entering and calculating the measured values in the formula below.

    ABS wheel speed sensor gap = B - A 

    ABS wheel speed sensor gap standard value: 

    0.3 - 0.8 mm (0.012 - 0.031 in) 

    NOTE: If clearance is outside of the standard value, readjust by using the spacer (Part No. 26755AA000).
