| SQUEAK / CREAK NOISE FROM REAR – VEHICLES BUILT BEFORE 9/5/2006 |
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.
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.
- Remove rear quarter trim panels to expose the upper shock bushing.
- Remove upper shock rod nuts, washer and bushing.
- Pull down on shock rod from the outside of the vehicle to remove the lower bushing and provide clearance for drilling the bushing hole.
- 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)

Figure 1
- 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.

Figure 2
- Guide the shock rod and bushing through the hole and verify that the bushing is completely through the hole. (Figure 3)

Figure 3
NOTE: IT MAY BE NECESSARY TO HOLD THE TOP OF SHOCK ROD DURING TORQUE OPERATION TO ELIMINATE ROTATION OF SHOCK ROD.
NOTE: BUSHING WILL BE NOTICEABLY COMPRESSED MORE THAN THE STOCK BUSHING. (FIGURE 4)

Figure 4
- Repeat procedure for the other side.
- Reinstall the rear trim panels.

- DELIVERS LONG-LASTING, MARINE-GRADE LUBRICATION: Clings to metal like a magnet and resists pressure, friction, and washout; ideal for lubricating locks, hinges, cable pulleys, and marine components exposed to heavy loads, rain, salt spray, tidal moisture, or constant vibration on boats and coastal equipment.
- FREES RUSTED PARTS WITH DEEP PENETRATION: Industrial-strength penetrating oil releases corrosion on frozen bolts, marine fittings, and seized engine parts; penetrates to free up when other products fail in salty, humid, or wet environments on boats, farm tools, or machinery.
- PROTECTS ELECTRONICS AND PREVENTS GALVANIC CORROSION: Safe on circuits, battery terminals, and sensors, CorrosionX forms a dielectric film rated over 39,000 volts that displaces moisture and stops galvanic corrosion between dissimilar metals in harsh environments.
- QUALIFIED BY THE U.S. NAVY FOR ADVANCED MARINE CORROSION PROTECTION: Corrosion Technologies is the only manufacturer in the world with products — CorrosionX being the flagship — qualified under the Advanced Corrosion Preventive Compound military specification; protects outboards, terminals, and powerheads with a self-healing, moisture-blocking film.
- Boeshield Is Great For Use In Marine, Bicycles, Automotive, Tools, Rv'S, And Aviation
- Loosens Rusty And Corroded Parts And Is Safe On Paints, Any Metal Surfaces, Plastics, And Vinyl
- Flushes Out Dirt And Old Lubricants, Displaces Moisture, And Penetrates Moving Parts
- Dries To A Thin, Waxy Film That Clings To Metal For Months
- RELENTLESS RUST PROTECTION FOR ANY WEATHER: This self-healing barrier clings and protects metal through rain, seawater, and pressure washing; it won’t drip, wash away, or quit, making it a reliable shield in even the harshest outdoor conditions.
- BUILT TO PROTECT FOR YEARS, NOT MONTHS: From boat trailers to barn doors, this long-lasting formula keeps working for up to 5 years indoors and 2 years outside; perfect for anyone who needs reliable rust protection.
- IDEAL FOR HEAVY-DUTY ELECTRICAL CONNECTIONS: Designed for larger terminals and connectors like battery posts and grounding lugs, this thick, non-conductive formula provides lasting protection without harming sensitive components, perfect where rugged sealing is needed.
- STAYS FLEXIBLE, NEVER FLAKES OR CRACKS: Forget waxy sprays that dry out and break down, this rust shield flexes with your gear, staying active and bonded even when machinery shifts, vibrates, or takes a beating in the field.
- SMART SCIENCE THAT BLOCKS HIDDEN DAMAGE: Polar Bonding locks onto surfaces to stop corrosion before it starts, preventing electrolysis and galvanic damage in places you can’t even see, from engine bays to salty docksides.
