Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, OBD-II scanner, torque wrench, fluid catch pan.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Steering Rack

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove any underbody covers that restrict access to the steering rack.
3. Visually inspect the steering rack for any signs of damage, corrosion, or fluid leaks.
4. If leaks are present, note the location and severity.

3. Replace Steering Rack (if necessary)

Sub-steps:
1. Disconnect the steering column from the steering rack by removing the connection bolts.
2. Remove the tie rod ends from the steering knuckles using a ball joint separator tool.
3. Disconnect any hydraulic lines from the steering rack, collecting any fluid in a catch pan.
4. Unbolt the steering rack from its mounting points and remove it from the vehicle.
5. Install the new steering rack by reversing the removal steps and ensuring all connections are tight.
  - Torque specifications: Refer to the vehicle service manual for proper torque values.

4. Refill and Bleed Steering System

Sub-steps:
1. Refill the power steering reservoir with the recommended fluid type.
2. Start the engine and turn the steering wheel from lock to lock multiple times to bleed air from the system.
3. Check for any leaks after bleeding the system and ensure fluid levels are correct.

5. Final Checks

Sub-steps:
1. Reattach the negative battery terminal.
2. Lower the vehicle and perform a test drive to ensure proper steering operation.
3. Check the alignment and adjust if needed.
