ISSUE
Some 2011 Edge and MKX vehicles may exhibit a drift/pull right concern even though the tire pressures and wheel alignment settings are within
specifications.
ACTION
Follow the Service Procedure.
SERVICE PROCEDURE
1. Partially raise vehicle.
2. Spin all wheels and inspect for brake drag.
a. If brake drag is present, do not continue with this article. Refer to Workshop Manual (WSM), Section 206-05, for normal diagnostics.
b. If no brake drag is present, proceed to Step 3.
3. Swap front tires and wheels from side to side (LF to RF) and retest for a drift/pull to the right.
a. If the concern is resolved, return vehicle to customer.
b. If the concern is still present, proceed to Step 4.
4. Record wheel alignment settings to establish a baseline.
5. Remove the RH splash shield. Refer to WSM, Section 501-02.
6. Remove three (3) pushpin fasteners, seven (7) screws and the front splash shield.
7. Using a wax pencil, mark the position of the front subframe to the underbody at each of the mounting nut locations.
8. Remove the subframe mounting nuts, one at a time, and replace with new nuts leaving 2 threads exposed to allow for subframe movement.
a. Negative cross caster and positive cross camber will reduce vehicle drift right. Increasing negative cross caster is preferred over positive cross
camber.
9. Increase negative cross caster to achieve a minimum of -0.5 degrees, not to exceed -1.2 degrees cross caster. Increase positive cross camber to
achieve a minimum of +0.6 degrees, not to exceed +1.2 degrees cross camber. Right hand camber not to exceed -1.2 degrees.
a. To increase negative cross caster, rotate the subframe clockwise, as viewed from the bottom of the car, taking note of the left front subframe
bushing and the right rear subframe bushing. For every 1 mm (1/32") of lateral movement outboard of both the left front and right rear subframe
bushings, cross caster will increase by approximately 0.25 degrees.
b. To increase positive cross camber, slide the subframe to the right (passenger side). For every 1 mm (1/32") of lateral movement, cross camber
will increase approximately 0.15 degrees.
10. Torque subframe mounting nuts to 133 N.m (98 lb-ft).
11. Reset front toe to specifications. Refer to WSM, Section 204-00.
