Steering Column Replacement Commercial

1. Set the front wheels in the straight-ahead position.
2. Set the steering wheel in the locked position.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

3. Disconnect the negative battery cable.
4. Remove the steering wheel, if required. Refer to Steering Wheel Replacement .
5. Disconnect the transmission control linkage from the column. Refer to Shift Cable Replacement in Automatic Transmission.
6. Mark the relationship of the upper cardan joint yoke to the steering shaft.
7. Remove the upper cardan joint pinch bolt nut from the steering gear coupling shaft.
8. Remove the upper pinch bolt (3) and washer.



9. Remove the outer steering column support bracket bolts (3).
10. Remove the outer support bracket and the inner steering column support bracket bolts (1) and remove the inner bracket (2).
11. Remove the screws (9) from the cover (4) and the seal (5).
12. Remove the nut (6) from the steering column retainer.
13. Disconnect the steering column harness at the connectors.

Notice: Once the steering column is removed from the vehicle, the column is extremely susceptible to damage. Dropping the column assembly on the end could collapse the steering shaft or loosen the plastic injections, which maintain column rigidity. Leaning on the column assembly could cause the jacket to bend or deform. Any of the above damage could impair the columns collapsible design. Do NOT hammer on the end of the shaft, because hammering could loosen the plastic injections, which maintain column rigidity. If you need to remove the steering wheel, refer to the Steering Wheel Replacement procedure in this section.

14. Remove the steering column assembly. Rotate the column so that the shift lever clears the floor opening.

1. Lower the end of the steering column through the floor opening passing through the loosely positioned floor panel cover (4), the seal (5) , and the retainer (7).



2. Guide the steering shaft into the cardan joint yoke by lining up the marks made during removal.
3. Loosely install the inner support bracket (1) with the bolts, and the outer bracket with the bolts.
4. Tighten the bolts finger tight.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
