Solution

1. Preparation

Disconnect the negative battery terminal to ensure safety.
Gather tools: socket set, power steering fluid, OBD-II scanner, and power steering pressure gauge.

2. Check and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir under the hood.
2. Remove the cap and check the fluid level; add OEM-approved power steering fluid as needed.
3. If fluid is dirty or contaminated, proceed to flush the system.
4. Use a turkey baster to extract old fluid from the reservoir.
5. Refill with new power steering fluid and replace the cap.

3. Inspect and Replace Power Steering Pump (if necessary)

Sub-steps:
1. Remove any components obstructing access to the power steering pump.
2. Disconnect the power steering lines and electrical connector from the pump.
3. Unbolt the power steering pump from its mounting bracket using a socket set.
4. Install the new power steering pump, ensuring all bolts are torqued to manufacturer specifications.
5. Reconnect the power steering lines and electrical connector.

4. Check and Replace Steering Rack (if necessary)

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the front wheels to access the steering components.
3. Disconnect the tie rod ends from the steering rack.
4. Unbolt the steering rack from its mounts and remove it from the vehicle.
5. Install the new steering rack, reconnect the tie rod ends, and torque to specifications.
