ISSUE
Some 2006-2008 Explorer, Mountaineer and 2007-2008 Sport Trac vehicles built on or before 7/28/2008 may exhibit a high pitched squeal noise from the rear axle area while driving at low speeds. This may be caused by the rear outer axle halfshaft dust seals contacting the knuckle surface.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Position vehicle on a hoist and place it in neutral.
2. Remove the rear wheel and tire. For additional information, refer to Workshop Manual (WSM), Section 204-04.

4. Use the special tool, press the outboard constant velocity (CV) joint until it is loose in the hub. (Figure 2)
5. Use a brush and apply Motorcraft(R) Silicone Brake Caliper Grease and Dielectric Compound to lubricate the rear axle halfshaft dust seal.
