ISSUE
Some 2011-2012 Fusion vehicles equipped with 2.5L, 2.5L Atkinson or 3.0L engine and MKZ vehicles equipped 2.5L Atkinson engine and built between 2/1/2011 through 8/16/2011 may experience higher than expected friction in the rearward/half front lower control arms. The steering system senses the high friction condition and may illuminate the instrument cluster stability/traction control light, or the message center may display Steering Fault/Service Steering Soon, accompanied by diagnostic trouble codes (DTCs) PO7AE and U0415.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Verify the vehicle build date:
a. If the vehicle build date is prior to 2/1/2011 or after 8/16/2011, do not continue with this article. Refer to Workshop Manual (WSM), Section 204-01, for normal diagnostics.
b. If the vehicle build date is 2/1/2011 to 8/16/2011, proceed to Step 2.
2. Retrieve DTC codes:
a. If PO7AE and U0415 are not present and were not retrieved. Do not continue with this article. Refer to WSM, Section 204-01, for normal diagnostics.
b. If PO7AE and U0415 are present, proceed to Step 3.
3. Raise the vehicle on a hoist. Refer to WSM, Section 100-02. In order to obtain accurate measurement, the suspension must be in full rebound with the weight of the vehicle supported by the frame. Raise and support the vehicle by the frame to allow the wheels to hang in the rebound position.
4. Check both bellows at the steering gear housing/inner tie rod interface externally for signs of cuts or abrasions which may allow water intrusion into the gear assembly.
a. If damage to the bellows exists or water intrusion is evident, replace the electronic power assist steering (EPAS) gear assembly. Refer to WSM, Section 211-02.
b. If no damage exists, proceed to Step 5.
5. Replace both the left and right rearward/haft front lower control arms (FLCA). Refer to WSM, Section 204-01.
