Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, top up with the manufacturer-recommended fluid.
Inspect the fluid for contaminants or debris. If dirty, proceed to replace the fluid.

3. Inspect Power Steering Pump

Reconnect the battery.
Start the engine and turn the steering wheel from lock to lock.
Listen for any unusual noises. If the pump is noisy, it may need replacement.
Remove the pump by loosening the mounting bolts and disconnecting the hoses.

4. Examine Steering Rack and Components

Raise the vehicle using a jack and secure it with jack stands.
Inspect the steering rack and tie rods for any signs of damage or wear.
If damaged, remove the steering rack by detaching it from the subframe and disconnecting the tie rod ends.

5. Reassemble and Refill

Reinstall any components that were removed.
Refill the power steering fluid reservoir.
Bleed the power steering system to remove any air trapped in the lines by turning the steering wheel from lock to lock several times with the engine running.
