Solution

1. Preparation

Gather tools: socket set, torque wrench, screwdriver, fluid catch basin.
Park the vehicle on a level surface and ensure the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the recommended power steering fluid (check owner's manual for specifications).
Replace the cap securely.

3. Inspect and Replace Serpentine Belt (if necessary)

Locate the serpentine belt and inspect for cracks, fraying, or excessive wear.
If damaged, use a wrench to relieve tension on the tensioner and remove the old belt.
Route the new serpentine belt according to the belt routing diagram (usually found on a sticker in the engine compartment).
Ensure the belt is seated correctly on all pulleys and reapply tension.

4. Inspect and Replace Power Steering Pump (if necessary)

Remove the power steering pump by disconnecting the fluid lines and unbolting it from the engine.
Install the new power steering pump, ensuring all connections are tight and secure.
Refill the power steering fluid to the appropriate level.

5. Check Steering Rack and Pinion (if necessary)

Inspect the steering rack and pinion for any signs of leaks or physical damage.
If damage is found, remove the steering rack by disconnecting tie rod ends and unbolting it from the chassis.
Install a new steering rack and ensure proper alignment of tie rods before tightening bolts to the manufacturer’s torque specifications.
