Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, top off with the manufacturer-specified fluid (usually ATF or a specific power steering fluid).
Reinstall the cap securely.

3. Inspect Power Steering Components

Visually inspect all hoses connected to the power steering system for cracks or signs of wear.
Check the power steering pump for any leaks or damages.
If leaks are found, replace the affected hoses or the power steering pump as necessary.

4. Bleed the Power Steering System (if necessary)

With the engine running and front wheels off the ground, turn the steering wheel from lock to lock several times to release trapped air.
Recheck fluid level and add fluid if necessary.

5. Reassemble and Test

Reconnect the battery terminal.
Start the engine and check for fluid leaks.
Test drive the vehicle to ensure that the steering is functioning properly and that the steering wheel turns smoothly.
