Sensor, Wheel Speed, Front: Description

Courtesy of CHRYSLER GROUP, LLC

One Wheel Speed Sensor (WSS) is mounted to each knuckle. The WSS, using a tone wheel attached to the hub and bearing as a trigger mechanism, communicates with the Antilock Brake Module (ABM), informing it of that wheel's speed.

The head of the front WSS mounts to the inside of the knuckle.
