- Steering Rack and Pinion:
  - Disconnect the battery.
  - Remove the tie rod ends from the steering rack.
  - Unbolt the steering rack from the chassis.
  - Install the new steering rack and torque bolts to manufacturer specifications.
- Tie Rod Ends and Ball Joints:
  - Use a ball joint separator to disconnect any affected tie rods or joints.
  - Replace with new parts and ensure they are properly torqued.

4. Wheel Alignment

After replacing any components, perform a wheel alignment.
- Use an alignment rack to adjust camber, caster, and toe settings to manufacturer's specifications.

5. Final Checks

Reconnect the battery and start the engine.
