Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to ensure safety during the repair.
Lay down a protective covering under the vehicle to catch any fluid spills.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check fluid level; if low, top up with the recommended fluid (Toyota PS Fluid).
3. If the fluid is dirty or contaminated, drain the old fluid using a turkey baster or fluid extractor.
4. Refill with new power steering fluid to the appropriate level.

3. Check and Replace Power Steering Pump

Sub-steps:
1. Disconnect the power steering pump belt by loosening the tensioner and removing the belt.
2. Remove the pump from its mounting by unscrewing the bolts and disconnecting the hoses.
3. Install the new pump by reversing the removal process.
4. Ensure all connections are tight and secure, and reattach the belt.

4. Inspect and Repair Steering Rack

Sub-steps:
1. Remove any components obstructing access to the steering rack (such as the air intake or undercarriage panels).
2. Inspect the steering rack for leaks, wear, or damage.
3. If damaged, remove the rack by unscrewing the mounting bolts and disconnecting the tie rods.
4. Install a new steering rack by reversing the removal process and ensuring proper alignment.

5. Final Checks

Sub-steps:
1. Refill the power steering fluid reservoir.
2. Start the engine and turn the steering wheel from lock to lock to purge air from the system.
3. Check for leaks around all connections and ensure the noise has stopped.
