ISSUE:
Steering drift/wander may occur in some new vehicles. This may be caused by high friction between components, excessive toe-in or high tire pressure.
In some cases, normal break-in of the vehicle will reduce component friction to an acceptable level.
ACTION:
Use the following diagnostic procedure to identify the concern and, if necessary, install front lower arm shim washers to correct the sensitive steering
condition.
1.
Confirm the concern with a test drive. Be aware that...
^
Higher than usual friction makes minor steering adjustments more frequent.
^
The friction may mask the aligning torque provided by suspension and tires.
^
The steering center friction may cause memory steer and for slight steering adjustments, the steering wheel center may have a small range of
locations.
2.
Before repair, make a hoist inspection of the vehicle for any damaged or improperly installed suspension or steering components.
3.
Verify that the vehicle has proper ride heights and ride attitude.
4.
To correct any discrepancies noted or for other potential causes of steering system complaints, refer to the Steering Diagnostic Section of the
appropriate Service Manual.
