Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely elevated using jack stands.
Wear safety gloves and goggles.

2. Locate the Leak

Sub-steps:
- Clean the affected area with a degreaser to remove any old fluid and debris.
- Inspect all hoses connected to the power steering system for cracks or loose fittings.
- Examine the power steering pump for signs of wear or leaks.

3. Replace Damaged Components

Sub-steps:
- If hoses are damaged, remove the old hoses using a socket set and replace them with new ones.
- If the power steering pump is leaking, disconnect the hoses and unbolt the pump from its mounting. Install a new pump and reconnect hoses, ensuring all connections are secure.
- If the steering rack is leaking, it may need to be replaced, which involves disconnecting it from the vehicle and installing a new unit.

4. Refill and Bleed the System

Sub-steps:
- Refill the power steering fluid reservoir with the recommended fluid type (consult the owner’s manual for specifications).
- 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 top off as necessary.
