Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, top off with the recommended power steering fluid (usually ATF Dexron III or equivalent).

3. Check for Leaks

Visually inspect the power steering lines for any signs of wear, cracks, or leaks.
If leaks are found, replace the damaged hoses or connections.
Clean any spilled fluid thoroughly to prevent slipping.

4. Inspect and Replace Steering Rack (if necessary)

Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels to access the steering components.
Disconnect the inner tie rod ends from the steering rack.
Unbolt and remove the steering rack from its mounting position.
Install the new or rebuilt steering rack, ensuring proper alignment and torque specifications (generally around 30-40 ft-lbs).

5. Test Power Steering Pump

Reconnect the power steering pump if disconnected.
Start the engine and let it idle while turning the steering wheel left and right.
Listen for any abnormal noises; replace the pump if it sounds noisy or is not supplying fluid.

6. Reassemble and Refill

Reinstall the front wheels and lower the vehicle.
Refill the power steering reservoir to the proper level.
Reconnect the negative battery terminal.
