If leaks are found, replace the damaged hose(s) or fittings.
Check the power steering pump for any signs of damage or excessive noise while the engine is running.

5. Replace Power Steering Pump (if necessary)

Tools Required: Socket set, torque wrench, new power steering pump
Remove the power steering belt using a wrench to loosen the tensioner.
Disconnect the hoses from the pump and remove the pump from its mounting.
