Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Locate the Leak Source

Tools Required: UV dye kit, black light (optional)
Inspect the power steering hoses, pump, and rack using the visual check. If necessary, add UV dye to the fluid and run the engine to circulate it. Use the black light to locate the source of the leak.

3. Replace Damaged Components

Tools Required: Socket set, wrench set, fluid catch basin

If the leak is from a hose, use a socket set to disconnect the hose clamps and remove the damaged hose.
Replace it with a new hose, ensuring it fits snugly and is secured with the clamps.
If the pump is leaking, remove the mounting bolts using a socket set, disconnect the inlet and outlet lines, and replace the pump with a new one.
If the steering rack is leaking, it may require complete replacement. Disconnect the steering linkage and remove the mounting bolts; replace it with a new rack.

4. Refill Power Steering Fluid

Tools Required: Funnel

After replacing any damaged components, refill the power steering fluid reservoir with the recommended type of fluid (check the owner's manual for specifications).
Ensure the fluid level is correct.

5. Bleed the Power Steering System

Tools Required: None

Start the engine and turn the steering wheel from lock to lock several times to purge air from the system.
Check the fluid level again and add more if necessary.
