3. Remove the 2 lower steering column shaft joint cover nuts and the cover.

4. NOTICE: Make sure to correctly index-mark the steering gear-to-steering column shaft position or unequal right-to-left turns may occur, causing tire contact with the body and/or clockspring damage.

Index-mark the steering column shaft-to-steering gear position for reference during installation.





5. NOTICE: Do not allow the steering column to rotate while the steering column shaft is disconnected from the steering gear or damage to the clockspring may occur. If there is evidence that the steering column has rotated, the clockspring must be removed and recentered. For additional information, refer to Restraint Systems.
