Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on the electrical system.

2. Inspect Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, add manufacturer-recommended power steering fluid as needed.
Check the fluid condition; if it appears dark or contaminated, a fluid flush may be required.

3. Check for Leaks

Visually inspect all hoses and connections from the power steering pump to the steering rack for any signs of leaks.
Use a flashlight to inspect underneath the vehicle, looking for signs of fluid pooling.
If leaks are found, replace the damaged hoses or seals.

4. Inspect Power Steering Pump

Using a socket set, remove any brackets or covers obstructing access to the power steering pump.
Check for proper operation by spinning the pulley; it should turn smoothly without resistance.
If the pump is faulty, replace it with a new unit. Torque the mounting bolts to the manufacturer's specification.

5. Inspect Suspension Components

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect the tie rods, control arms, and strut mounts for any signs of damage or wear.
If components are damaged, replace them accordingly, ensuring to torque all bolts to the specified values.

6. Reassemble and Test

Reattach any components removed during inspection and ensure all bolts are tightened to specification.
Reconnect the battery and start the engine.
Test the steering wheel for improved operation.
