STEERING NOISE - CLUNK/RATTLE

FORD:
2005-2007 Escape

MERCURY:
2005-2007 Mariner

This article supersedes TSB 05-25-9 to update the vehicle model years.

ISSUE
Some 2005-2007 Escape and Mariner vehicles may exhibit a single or multiple clunk/rattle noise from the front end. This noise typically occurs with the front wheels turned while hitting a bump such as when turning into a driveway. It is usually more noticeable with hot engine and ambient air temperatures, and may easily be mistaken for loose sheet metal or a loose suspension/underhood component. The cause of this noise is an audible hydraulic pressure spike in the power steering system.

ACTION
Install a new power steering return line which contains an internal orifice to reduce the pressure spike.

SERVICE PROCEDURE
1. Remove the power steering reservoir cap.

2. Using a suitable suction device, remove the power steering fluid from the reservoir.

3. Disconnect the power steering return hose from the reservoir by loosening the constant tension clamp.

4. Remove and discard the lower return line hose clamp, then remove the hose.

5. Install the new return line with the crimped band away from the reservoir. The pre-installed constant tension clamp will retain the reservoir end of the hose.

6. Install and tighten the screw clamp on the lower end of the hose.

7. Refill the system with Mercon® or Mercon(R)-V fluid and purge the air as described in Section 211-00 of the Workshop Manual.
NOTE
DO NOT FILL WITH TYPE-F FLUID.
