Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Disconnect the battery to prevent electrical issues while working on the vehicle.

2. Check and Refill Power Steering Fluid

Locate the power steering reservoir, typically found near the engine.
Remove the reservoir cap and check fluid level against the dipstick.
If low, add the manufacturer-recommended power steering fluid until the proper level is reached.
Inspect for leaks around hoses and connections.

3. Inspect and Replace Power Steering Pump (if required)

Remove the serpentine belt from the power steering pump pulley using a socket set.
Disconnect the power steering pump lines and cap the openings to prevent fluid leakage.
Remove mounting bolts and take out the old pump.
Install the new power steering pump, ensuring it is securely mounted.
Reconnect the pump lines and the serpentine belt, following torque specifications.

4. Check Steering Components

With the vehicle on a lift, inspect tie rods and steering rack for any signs of wear or damage.
Replace any damaged components with OEM parts.
Reassemble any components that were removed for inspection.

5. Wheel Alignment

After repairs, perform a wheel alignment to ensure proper steering geometry.
Adjust as necessary to bring the vehicle back to factory specifications.
