Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, wrench set, fluid catch pan, and flashlight.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Power Steering Fluid

Open the hood and locate the power steering reservoir.
Remove the cap and check the fluid level; if low, add the recommended fluid type (check owner's manual for specifications).
If the fluid is dark or contaminated, drain the old fluid using a fluid catch pan and replace it with new fluid.
Recheck the fluid level and replace the cap securely.

3. Inspect and Repair Power Steering System

Examine all hoses and connections for signs of wear or leaks; replace any damaged components.
If the power steering pump is leaking or making noise, it may need to be replaced. To replace:
1. Disconnect the power steering hoses from the pump (use a wrench to avoid damaging the fittings).
2. Remove the mounting bolts securing the pump to the engine.
3. Install the new pump by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.
4. Reconnect the power steering hoses and check for leaks.

4. Inspect Steering Rack and Components

Check the steering rack for any signs of damage or wear.
Inspect tie rod ends for play or damage; replace if necessary.
If the steering rack is faulty, consult the service manual for specific removal and installation instructions.
