Lower/Upper Intermediate Steering Shaft Replacement Commercial

1. Set the front wheels in the straight-ahead position.
2. Set the steering wheel in the locked position.
3. Mark the relationship of the following components in order to ensure proper installation:

•	The steering gear coupling shaft to the steering shaft

•	The cardan joint yoke to the steering gear input shaft

4. Remove the upper and the lower pinch bolts (2) and nuts at the cardan joint yoke.
5. Remove the steering gear coupling shaft assembly by compressing the shaft up (toward the steering column) in order to clear the cardan joint yoke from the steering gear input shaft.
6. Slide the shaft down off of the upper steering shaft.

You may have to tap on the yoke with a small hammer in order to free the yoke from the shaft.

1. Align the marks on the steering gear coupling and the steering shaft.
2. Install the upper end of the steering gear coupling shaft onto the upper steering shaft.
3. Install the lower end of the steering gear coupling shaft onto the steering gear input shaft.

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.

4. Install the upper and the lower pinch bolts (2) and nuts at the cardan joint yokes.

Ensure that the pinch bolts pass through the shaft undercut.

Tighten
Tighten the pinch bolts to 102.5 N·m (76 lb ft).
