Here is a portion of the TSB. I only posted a portion of it.
You might ask them if it pertains to your problem.
Steering - Vehicle Pulls/Drifts to the Left/Right
October 4, 2007
Vehicle Pulling or Drifting
(Supersedes 06-068, dated January 12, 2007, to update the information marked by asterisks)
While driving on a straight road, the vehicle pulls or drifts to the right or left.
New tools were developed to help you diagnose and correct a pulling and/or steering wheel off-center issue. There is a diagnosis worksheet included to take on your test-drive and record your findings. These values are used to build the 15-digit DTC (diagnostic trouble code) that is required for your warranty claim. The last step in each repair procedure helps you create the correct code.
In the rare case that you have to repair a vehicle that pulls and has the steering wheel off-center, use REPAIR PROCEDURE B to file your warranty claim.
*For more information, refer to Training Module SSC 44 - Steering Drift or Pull Interactive Service Bulletin.*
Several conditions can cause the vehicle to pull or drift:
^ Wheel alignment
^ Steering wheel off-center (no pulling or drifting, but a customer may believe this is the case)
Diagnose the problem using the special tools and the worksheet on page 4 that guides you to one of four repair procedures.
REPAIR PROCEDURE B
1. Place the vehicle on a commercially available, computerized, four-wheel alignment rack, and record the following measurements. Follow the equipment manufacturer's instructions.
NOTE :Enter each reading in decimal degrees. Example 30' = 0.5°.
2. If any measurement is out of specification, inspect the front suspension for any damage. Repair the damaged components before continuing your diagnosis.
3. Determine how the front wheel camber is affecting the pull. Pick the combination of left- and right-front camber that best matches the vehicle you are repairing, then note the camber thrust direction for that combination:
4. Determine how the camber needs to be adjusted.
5. Adjust the camber as needed.
Front Camber Adjustment, Double Wishbone Suspension
^ Loosen the front subframe bolts. See the applicable service manual for more information.
NOTE :The front wheels are being viewed from the rear of the vehicle.
^ Depending which way you need to shift the subframe, insert a pry bar between the subframe and body at both the front and rear positions of the subframe.
NOTE :Be careful not to damage the vehicle. You could bend and damage the frame and/or body if you apply too much pressure.
^ Press on both pry bars to shift the subframe. It will move only a few millimeters. This should adjust the camber about 0.2-0.5°.
^ While holding the subframe in place, have an assistant torque the subframe bolts to their proper torque.
