Solution

1. Preparation

Gather tools and materials including a fluid catch pan, power steering fluid, and a socket set.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery for safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, add the recommended power steering fluid (refer to owner's manual for the specification).
Replace the cap securely.

3. Inspect and Replace Power Steering Hoses

Use a socket set to remove any clamps securing the power steering hoses.
Inspect the hoses for cracks, bulges, or leaks.
If damaged, replace the hoses with OEM or high-quality aftermarket parts.
Reattach the hoses and secure with clamps.

4. Test and Replace Power Steering Pump (if necessary)

With the engine on, listen for any unusual noises from the pump.
Connect a pressure gauge to the pump outlet to check for proper pressure (refer to specifications for pressure values).
If pressure is below specifications or if the pump is noisy, replace the power steering pump.
To replace:
1. Disconnect the inlet and outlet hoses from the pump.
2. Remove any mounting bolts securing the pump.
3. Install the new pump and secure it with bolts; torque to manufacturer specifications.
4. Reconnect the hoses and check for leaks.

5. Verify Steering Rack and Pinion

If issues persist, inspect the steering rack and pinion for damage.
Remove any protective covers if needed to access the rack.
Look for signs of wear or fluid leaks.
If damaged, replace the steering rack according to the manufacturer's instructions.
