Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery to ensure safety.

2. Inspect 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 manufacturer-recommended power steering fluid until it reaches the proper level.
Reattach the cap securely.

3. Inspect Power Steering Pump

Locate the power steering pump, typically near the engine.
Check for any fluid leaks around the pump.
With the engine running, listen for whining noises indicating a failing pump.
If the pump is faulty, proceed to replace it:
- Disconnect the power steering lines (ensure to have a drain pan ready for fluid).
- Unbolt the pump from its mounting brackets.
- Install the new pump by reversing these steps and ensuring all connections are secure.

4. Check Steering Rack and Pinion

Raise the front of the vehicle using a jack and secure it with jack stands.
Inspect the steering rack for any visible leaks or damage.
Check the tie rod ends for excessive play or wear; replace if necessary.
If the steering rack is defective, replace it:
- Disconnect the steering linkage and any associated electrical connectors.
- Unbolt the rack from the vehicle and install the new rack following reverse steps.

5. Inspect Serpentine Belt

Check the condition of the serpentine belt for cracks or wear.
If the belt is damaged, remove it:
- Release tension using a belt tensioner tool.
- Install a new serpentine belt according to the routing diagram found on the engine cover.
