3. Remove any bolts securing the rack to the subframe.
4. Slide the rack out and replace it with a new or remanufactured steering rack.
5. Reinstall the steering linkage and secure all bolts to manufacturer torque specifications.

5. Final Assembly and Fluid Refill

Sub-steps:
1. Reinstall any components removed during the inspection and repair process.
2. Refill the power steering fluid reservoir to the proper level.
3. Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
