If leaks are present, replace the affected components (hoses, pump, etc.).
Tighten any loose connections.

4. Examine Power Steering Pump

With the engine running, listen for abnormal sounds from the power steering pump.
If the pump is noisy or not functioning, replace it as necessary.
Ensure the pump is properly aligned and the mounting bolts are secured to the manufacturer’s torque specifications.

Check the condition of the power steering belt for cracks or wear.
If damaged, replace the belt.
Ensure the belt tension is within manufacturer specifications.
