ISSUE
Some 2008-2010 Escape and Mariner vehicles may exhibit a vibration or nibble in the steering wheel while driving at 55-75 MPH (88-121 Km/h) in
cold ambient temperatures of 5-25 °F (-15 to -4 °C). The vibration/nibble may be perceived as a tire or driveshaft balance issue. A steering wheel
damper has been developed to correct this condition.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Check and adjust tire air pressure as required. Refer to the Workshop Manual (WSM), Section 204-04.
2. Install the Rotunda Mastertech MTS-4000 Analyzer (257-00018) or equivalent.
3. Road test the vehicle for 15 minutes and record the vibration frequency.
a. If the vibration goes away during the test drive, discontinue this procedure. The concern is due to temporary tire flat spotting which is a normal
tire condition. Refer to WSM, Section 204-04.
b. If the vibration remains and the vibration frequency is within the range of 27-33 Hz proceed to Step 4.
c. If the vibration frequency not within the range of 27-33 Hz, do not continue with this procedure. Follow normal WSM diagnostic. Refer to WSM,
Section 100-04.
4.
Install a revised steering wheel damper.
a. Remove steering wheel. Refer to the WSM, Section 211-04.
b. Remove the trim cover from the rear of the steering wheel.
c. Remove the three (3) damper bracket screws from the steering wheel and remove steering damper. (Figure 1)
d. Attach revised steering wheel damper using existing screws.
