1. Preparation

Gather tools: socket set, wrench set, screwdriver, jack and jack stands, fluid catch pan.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Power Steering Fluid

3. Inspect and Replace Steering Components

Sub-step 1: Raise the front of the vehicle using a jack and secure it on jack stands.
Sub-step 2: Visually inspect the steering rack for any signs of leaks or damage. If damaged, remove and replace the steering rack.
Sub-step 3: Check the tie rods and ball joints for excessive play or wear. Replace any components that show signs of damage.
Sub-step 4: Inspect the universal joint and intermediate shaft. If there is binding or wear, replace the affected components.

4. Reassemble and Test

Sub-step 1: Reconnect any components removed during inspection (steering rack, tie rods, etc.).
Sub-step 2: Lower the vehicle from the jack stands and reconnect the negative battery terminal.
Sub-step 3: Start the engine and turn the steering wheel to check for any remaining noises.
