1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical issues.

2. Remove the Power Steering Fluid Reservoir

Locate the power steering fluid reservoir.
Using a socket set, remove the bolts securing the reservoir.
Disconnect the hoses from the reservoir, allowing any remaining fluid to drain into a container.

Hoses: Replace any leaking or damaged hoses. Use new power steering hoses that match the original specifications.
Pump: If the pump is leaking, remove it by disconnecting the supply and return lines and unbolting it from the engine. Install the new pump, ensuring all connections are tight.
Steering Rack: If the steering rack is leaking, it may need to be replaced. Remove the tie rod ends and disconnect the rack from the vehicle. Install the new steering rack according to the manufacturer's specifications.

4. Reassemble the System

Reconnect all hoses and ensure they are secured tightly.
Reinstall the power steering fluid reservoir and secure it with bolts.
Reconnect the battery.

5. Refill and Bleed the Power Steering System

Fill the power steering reservoir with the recommended fluid type.
Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
Check fluid levels and add more fluid if necessary.
