Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is on a flat surface and securely lifted with jack stands if necessary.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Refill Power Steering Fluid

Locate the power steering reservoir and check the fluid level.
If low, add the manufacturer-recommended power steering fluid until it reaches the proper level.
Check the fluid condition; if it appears dark or contaminated, plan for a fluid flush.

3. Repair or Replace Leaking Components

Identify any leaks in the power steering hoses and seals.
Use a wrench to disconnect the leaking hoses and replace them with new ones.
If the steering rack is leaking, remove it by:
1. Disconnecting the steering linkage.
2. Removing the mounting bolts.
3. Disconnecting the fluid lines.
4. Installing the new steering rack and reconnecting all components.

4. Align Steering Components

If the steering rack and tie rods are in good condition, check the alignment.
Adjust the alignment using an alignment machine or take it to a professional alignment shop.
Ensure the steering angle sensor is recalibrated if necessary.

5. Reconnect and Test

Reconnect the battery and start the vehicle.
Test the steering for responsiveness and check for any abnormal noises.
If necessary, recheck fluid levels and top off again.
