ISSUE
Some 2009 Escape, Mariner, Escape Hybrid and Mariner Hybrid vehicles built from 10/21/2008 to 10/31/2008 may exhibit a clicking or rubbing noise from the left front wheel speed sensor and/or exhibit ABS warning light activation. The left front wheel knuckle may have been machined incorrectly allowing the wheel speed sensor to contact the tone ring.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

1. Measure the air gap between the left front wheel speed sensor and tone ring with a feeler gage.

2. If 0.02" (0.50 mm) or more - this procedure does not apply. Continue with normal diagnostics.

3. If less than 0.02" (0.5 mm) or evidence of contact - replace the left front wheel knuckle per Workshop Manual (WSM), Section 204-01 and the left front Wheel Speed Sensor per WSM, Section 206-09.
