Conduct a visual inspection of the hoses and connections for signs of fluid leakage.
If leaks are found, replace the damaged hoses or fittings.
Tighten any loose connections that may be contributing to the leak.

4. Replace Power Steering Pump (if necessary)

Remove the drive belt connected to the power steering pump using a socket set.
Disconnect the power steering lines from the pump; use a container to catch any leaking fluid.
Remove the power steering pump mounting bolts and take out the pump.
Install the new power steering pump in reverse order of removal, ensuring all connections are secure.
Reattach the drive belt and ensure proper tension.

5. Bleed the Power Steering System

Fill the power steering reservoir with the appropriate fluid.
Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
Check fluid level again and top off if necessary.
