If leaks are found, replace the damaged hoses or fittings.
Clean the area around the leak to confirm if the issue is resolved after repairs.

4. Test Power Steering Pump

Reconnect the battery.
Start the engine and let it idle.
Turn the steering wheel from lock to lock to listen for abnormal noises.
If the pump is noisy or not functioning properly, replace the power steering pump.
