Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure the engine is off.
Disconnect the negative battery terminal to prevent accidental electrical shorts.

2. Inspect and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check fluid level; add manufacturer-approved fluid if low.
If the fluid is contaminated, proceed to flush and replace it.

3. Check Serpentine Belt

Inspect the serpentine belt for cracks, wear, or fraying.
If damaged, remove the belt by loosening the tensioner pulley using a socket and ratchet.
Replace with a new belt, ensuring proper alignment and tension.

4. Inspect Steering Components

Raise the vehicle using a jack and secure with jack stands.
Check the tie rod ends for play by moving them up and down; replace if worn.
Inspect the ball joints for movement and cracks; replace if necessary.
If the steering rack is found to be leaking or damaged, it will need to be replaced.

5. Reassemble and Test

Reassemble any components removed during inspection.
Reconnect the negative battery terminal.
Start the engine and turn the steering wheel fully left and right to bleed the power steering system.
Test drive the vehicle to ensure the squeaking noise has been resolved.
