ISSUE
Some 2007-2008 Ford Edge and Lincoln MKX vehicles may exhibit a drift/pull concern that occurs even though the tire pressures and wheel alignment are within specifications, and the concern is not corrected by rotating the front tires left to right.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
Verify that drift/pull is not being caused by concerns listed in Workshop Manual (WSM), Section 204-00 drift/pull diagnostics. If normal drift/pull WSM diagnostics/procedures do not resolve the concern then refer to the following service steps.
NOTE
THIS SERVICE PROCEDURE MAY CAUSE THE FRONT CROSS CAMBER (TOTAL/SPLIT) ALIGNMENT VALUE TO EXCEED THE SERVICE MANUAL SPECIFICATION OF 0.00 +/- 0.75 DEGREES. DO NOT EXCEED +/- 1.2 DEGREES OF CROSS CAMBER.
For a Right Drift/Pull
1. Inspect the left strut upper plate to verify which direction the arrow is pointing. (Figure 1)
NOTE
IF THE NOTCH IS VISIBLE IN THE ACCESS HOLE IN THE STRUT TOWER, THE PLATE HAS ALREADY BEEN ROTATED A POSITIVE 0.5 DEGREE.
2. If the arrow is pointing inboard as seen through the access hole in Figure 1, no rotation is necessary (positive 0.5 degree camber already there). Continue with Step 4.
3. If the arrow is pointing outboard, increase positive camber approximately 0.5 degrees on the left front wheel by rotating the upper strut plate 180 degrees. Refer to WSM, Section 204-00, Camber Adjustment - Front.
NOTE
DISCONNECT THE FRONT STABILIZER BAR LINK AT THE LOWER CONTROL ARM SO THAT ENOUGH CLEARANCE CAN BE OBTAINED TO ROTATE THE UPPER STRUT MOUNT. REPLACE THE STABILIZER BAR LINK NUT ON REASSEMBLY.
NOTE
REPLACE THE FOUR (4) UPPER STRUT MOUNT NUTS.
4. Place vehicle on alignment rack. Remove and replace the two (2) right front shock absorber (strut) to wheel knuckle lower flag bolts and nuts but do not tighten. Refer to WSM, Section 204-01.
5. With full vehicle weight on the wheels allow the right wheel to increase negative camber and tighten both lower flag bolts and nuts to 166 lb-ft (225 N.m). The camber shift may vary between vehicles, but will typically be between a negative 0.2 and negative 0.6 degrees of camber change. Refer to WSM, Section 204-01.
6. Reset front toe adjustment to proper specifications. Refer to WSM, Section 204-00, Toe Adjustment - Front.
For a Left Drift/Pull
1. Inspect the right strut upper plate to verify which direction the arrow is pointing. (Figure 1)
NOTE
IF THE NOTCH IS VISIBLE IN THE ACCESS HOLE IN THE STRUT TOWER, THE PLATE HAS ALREADY BEEN ROTATED A POSITIVE 0.5 DEGREE.
2. If the arrow is pointing inboard, as seen through the access hole in Figure 1, no rotation is necessary (positive 0.5 degree camber already there). Continue with Step 4.
3. If the arrow is pointing outboard, increase positive camber approximately 0.5 degrees on the right front wheel by rotating the upper strut plate 180 degrees. Refer to WSM, Section 204-00, Camber Adjustment - Front.
NOTE
DISCONNECT THE FRONT STABILIZER BAR LINK AT THE LOWER CONTROL ARM SO THAT ENOUGH CLEARANCE CAN BE OBTAINED TO ROTATE THE UPPER STRUT MOUNT. REPLACE THE STABILIZER BAR LINK NUT ON REASSEMBLY.
NOTE
REPLACE THE FOUR (4) UPPER STRUT MOUNT NUTS.
4. Place vehicle on alignment rack. Remove and replace the two (2) left front shock absorber (strut) to wheel knuckle lower flag bolts and nuts but do not tighten. Refer to WSM, Section 204-01.
5. With full vehicle weight on the wheels allow the left wheel to increase negative camber and tighten both lower flag bolts and nuts to 166 lb-ft (225 N.m). The camber shift may vary between vehicles, but will typically be between a negative 0.2 and a negative 0.6 degrees of camber change. Refer to WSM, Section 204-01.
6. Reset front toe adjustment to proper specifications. Refer to WSM, Section 204-00, Toe Adjustment - Front.
