Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir and remove the cap.
2. Check fluid level; if low, add the manufacturer-recommended fluid type.
3. If the fluid is dark or contaminated, drain and replace it:
  - Place a drain pan under the steering rack.
  - Disconnect the return line and allow fluid to drain.
  - Reconnect the line and refill the reservoir with fresh fluid.

3. Replace Steering Rack (if necessary)

Sub-steps:
1. Raise the vehicle and secure it with jack stands.
2. Disconnect the steering shaft from the steering rack by removing the bolt securing it.
3. Remove the tie rod ends by loosening the nuts and using a puller if necessary.
4. Unbolt the steering rack from its mounting points.
5. Remove the old steering rack and install the new one, ensuring proper alignment.
6. Reconnect the tie rod ends and steering shaft.
7. Fill the power steering system with fluid and bleed it per the manufacturer’s guidelines.

4. Reassemble and Test

Sub-steps:
1. Lower the vehicle and reconnect the battery terminal.
2. Start the vehicle and turn the steering wheel slowly from lock to lock to bleed air out of the system.
3. Check for leaks and ensure the fluid level is correct.
