General Information

The mass balance spring (arrow) should be disconnected when work is performed on the upper steering column. Use caution as the mass balance spring is under extreme tension. Be careful not to bend the spring tab mounting retainers. Only the ignition starter switch, the lock cylinder and the Steering Angle Sensor (LWS) can be replaced as separate components on the upper steering column. See Fig 1 .
