Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid catch pan, power steering fluid, pressure gauge.
Gather all necessary replacement parts if required based on diagnostic findings.

2. Addressing Fluid Leaks

Sub-step 1: Clean the area around the steering rack to identify the source of the leak.
Sub-step 2: If leaks are found in hoses, remove the affected hose using a socket set and replace it with a new one.
Sub-step 3: If the steering rack itself is leaking, remove it by disconnecting the tie rods and any mounting bolts. Replace with a new steering rack, ensuring all connections are secure.

3. Replacing Power Steering Fluid

Sub-step 1: Remove the power steering fluid reservoir cap and drain the old fluid into a catch pan.
Sub-step 2: Refill with the manufacturer-recommended power steering fluid, ensuring no contaminants enter the system.
Sub-step 3: Reconnect the reservoir cap securely.

4. Testing and Calibration

Sub-step 1: Start the engine and turn the steering wheel from lock to lock to bleed the system of air.
Sub-step 2: Check for any leaks and ensure the steering feels smooth and responsive.
