Remove the pump:
- Unbolt the power steering pump from its mount using a socket set.
- Disconnect electrical connections and hoses carefully.
Inspect the pump:
- Check for signs of wear, such as leaks or noise when rotated by hand.
Install the new pump (if replacement is needed):
- Position the new pump in place and secure it with bolts to the mount.
- Reconnect hoses and electrical connectors.

4. Refill Power Steering Fluid

Use the manufacturer-recommended power steering fluid.
Fill the reservoir to the appropriate level indicated on the dipstick.

5. Bleed the Power Steering System

Start the engine and turn the steering wheel from lock to lock several times.
Check the fluid level and add more if necessary.
Look for any air bubbles in the reservoir; continue bleeding until bubbles are gone.

6. Verification

Test drive the vehicle to ensure smooth steering operation.
Listen for any unusual noises while turning the steering wheel.
Check for leaks around the pump and hose connections.
