GM Lumina/Silhouette/Transport APVs 1990-1999 Repair Guide

Rear Wheel Speed Sensor

Print

The rear wheel speed sensors operate in the same manner as the front wheel speed sensors. However, the wheel speed sensor and toothed ring are contained within the dust cap of the integral rear wheel bearing. The sensor and toothed ring are not repairable and no provision for air gap adjustment exists. If a rear wheel speed sensor fails, the entire integral bearing and speed sensor assembly must be replaced. For replacement procedures, please refer to Suspension and Steering of this repair guide.
