- Identify the leaking hose (high-pressure or return hose).
- Using a socket set, disconnect the hose from the power steering pump and steering rack.
- Replace the hose with a new one and tighten connections to manufacturer specifications.
Power Steering Pump
- If the pump is leaking, remove the drive belt using a belt tensioner tool.
- Unbolt the pump from its mounting bracket and disconnect the hoses.
- Install the new pump and reconnect hoses, ensuring there are no leaks.

3. Refill and Bleed Power Steering System

Fill the power steering reservoir with the manufacturer-recommended fluid.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid level and top off as necessary.
