Wheel Speed Sensor Air Gap

Raise vehicle, and remove wheel. Measure air gap between wheel speed sensor, rear of disc rotor, and each tooth of tone ring. Legacy tone rings have 44 teeth; SVX tone rings have 45 teeth. Front wheel air gap should be .039-.059" (1.00-1.50 mm) on Legacy and .028-.039" (.70-1.00 mm) on SVX. Rear wheel air gap should be .031-.051"(.78-1.30 mm) on Legacy and .020-.028" (.50-.70 mm) on SVX. Maximum hub/tone wheel runout is .002" (.05 mm).
If gap is too small, use Spacer (26755AA000) to increase gap to specification. If gap exceeds specification, remove spacer(s) or replace tone ring or faulty wheel speed sensor.
