Remove the rear ABS wheel-speed sensor.
Measure the distance between the rear ABS wheel-speed sensor installation surface and the rear ABS sensor rotor. This is dimension A.
Calculate the clearance between the rear ABS wheel-speed sensor and the rear ABS sensor rotor using the following formula:
Clearance (mm {in}) = A - 13.9 {0.547}
