Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative terminal of the battery for safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the markings on the reservoir.
If low, add the appropriate power steering fluid as per manufacturer specifications.
Replace the cap securely.

3. Inspect and Repair Leaks

Visually inspect hoses and connections for signs of leakage.
If leaks are found, replace damaged hoses or seals as necessary.
Use a power steering fluid dye to assist in identifying hard-to-find leaks if needed.

4. Test and Replace Power Steering Pump

Remove the drive belt from the power steering pump.
Test the power steering pump operation by turning the steering wheel; it should feel smooth without resistance.
If the pump is faulty, remove it using a socket set and replace it with a new one.
Reinstall the drive belt, ensuring it is tensioned correctly according to specifications.

5. Inspect Steering Rack

Raise the front of the vehicle using jack stands for access.
Check the steering rack for any visible damage or play in the joints.
If the steering rack is damaged, it will need to be replaced. Remove any necessary components to gain access, then unbolt the steering rack and install a new one.

6. Reconnect Battery and Test Drive

Reconnect the negative terminal of the battery.
Start the vehicle and turn the steering wheel from lock to lock to bleed air from the system.
Test drive the vehicle to ensure proper steering operation.
