Steering: arm

78V17200013,800 vehicles affected

The problem
The existing cross steering arms may have insufficient fatigue life in the neck area. This is near the boss for the cross steering tube ball joint connection. Failure of either of the cross steering levers could lead to loss of steering control of the right front wheel.
The fix
The dealer will inspect and, if necessary, install cross steering arms of improved design and greater strength.
