ISSUE
Some 2006-2007 Escape, Mariner, Escape Hybrid and Mariner Hybrid vehicles built before 9/5/2006 may exhibit a high pitched squeaking noise from
the rear upper shock bushing area. This concern is more noticeable while driving over small cracks or bumps during parking lot maneuvers. This may be
caused by the upper shock bushing coming out of position causing the shock rod to contact the body.
ACTION
Follow the Service Procedure steps to correct the condition by replacing the shock bushing.
NOTE
IT IS NOT NECESSARY TO REPLACE THE SHOCK ASSEMBLY.
SERVICE PROCEDURE
Verify noise is present by bouncing the parked vehicle from the rear and listening to the rear shock area. If inaudible, drive the vehicle and listen to the
rear shock area during parking lot maneuvers over small bumps. If noise is determined to be from the upper rear shock area, continue with repair
procedure.
1.
Remove rear quarter trim panels to expose the upper shock bushing.
2.
Remove upper shock rod nuts, washer and bushing.
3.
Pull down on shock rod from the outside of the vehicle to remove the lower bushing and provide clearance for drilling the bushing hole.
4.
Using a step drill bit (preferably one that stops at 7/8" or 22 mm) and drilling from inside the rear of the vehicle from the top down enlarge the
mounting hole to 7/8" (22 mm). (Figure 1) Drill bits may be obtained from the Rotunda Technician Tool Program (RTTP) tool number
VGP161O4 or a local tool supplier.
5.
De-burr the newly drilled hole and coat with Motorcraft® Low Temperature Anti-Corrosion Coating, PM-12-A.
NOTE
USE OF PM-12-A FOR THE ENLARGED HOLE IS ESSENTIAL TO PREVENT CORROSION IN THIS CRITICAL AREA EXPOSED TO
MOISTURE AND ROAD SALT.
