Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical issues.

2. Drain Power Steering Fluid

Place a drain pan under the power steering pump.
Disconnect the return line from the pump and allow the fluid to drain completely.
Reconnect the return line temporarily to avoid dirt entry while working on the pump.

3. Remove the Power Steering Pump

Remove any components obstructing access to the power steering pump, such as the engine cover.
Disconnect the high-pressure line from the power steering pump using a flare nut wrench.
Remove the mounting bolts securing the pump to the engine using a socket set.
Carefully lift the pump out of the engine bay.

4. Inspect and Replace Seals

Inspect the pump for any damaged seals or O-rings.
If seals are damaged, remove them using a seal puller.
Install new seals and O-rings, ensuring they are properly seated.

5. Reinstall the Power Steering Pump

Position the power steering pump back into place and secure it with mounting bolts. Torque the bolts to the manufacturer’s specifications (usually around 15-25 Nm, check your service manual).
Reconnect the high-pressure line and ensure it is tight.

6. Fill Power Steering Fluid

Reconnect the return line if it was temporarily disconnected.
Fill the power steering reservoir with the recommended power steering fluid as per the owner's manual.
Start the engine and turn the steering wheel from lock to lock several times to purge air from the system.

7. Check for Leaks

Inspect all connections and the pump for any signs of leaking fluid.
Monitor the power steering fluid level and top off if necessary.
