Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Gather safety equipment such as gloves and safety glasses.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, add the appropriate type of power steering fluid as specified in the owner's manual.

3. Inspect and Repair Leaks

Visually inspect all hoses and connections for signs of wear or leaks.
If any hoses are cracked or damaged, replace them:
- Disconnect the old hose using a wrench.
- Install the new hose, ensuring it is properly secured.
Clean any spilled fluid and monitor for new leaks.

4. Replace the Power Steering Pump (if necessary)

Disconnect the negative battery terminal to ensure safety.
Remove the drive belt from the power steering pump pulley.
Unbolt the pump from its mounting bracket.
Disconnect the fluid lines and remove the pump.
Install the new power steering pump by reversing the removal steps, ensuring all connections are tight.
Refill the power steering fluid reservoir.

5. Test Steering System

Reconnect the negative battery terminal.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
Check for any leaks around the pump and hoses.
