Solution

1. Preparation

Gather tools: socket set, rags, funnel, and a new bottle of power steering fluid.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety Warning: Always allow the engine to cool before performing maintenance.

2. Check and Refill Power Steering Fluid

Open the hood and locate the power steering reservoir.
Remove the cap and wipe the dipstick or check the fluid level.
If the fluid is below the recommended level, add the appropriate type of power steering fluid (check the owner’s manual for specifications).
Replace the cap securely.

3. Inspect Power Steering System

Visually inspect the power steering lines for any signs of wear, cracks, or leaks.
If leaks are present, proceed to replace the damaged hoses or fittings.
Check the condition of the power steering pump; if it is noisy or shows signs of failure, consider replacing it.

4. Bleed the Power Steering System (if needed)

With the engine running, turn the steering wheel from lock to lock several times to bleed air from the system.
Monitor the fluid level and add more fluid if necessary during this process.
