Tools Required: Socket set, fluid catch pan, funnel, and safety gloves.

2. Check and Refill Power Steering Fluid

Open the hood and locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, add manufacturer-recommended power steering fluid until it reaches the appropriate level.

Locate the power steering pump, which is typically mounted on the engine.
Tools Required: Socket set and torque wrench.
Disconnect the negative battery terminal to avoid electrical shorts.
Remove the serpentine belt from the power steering pump pulley.
Unbolt the pump from its mounting bracket and disconnect the fluid lines using a wrench.
Install the new power steering pump by reversing the removal steps, ensuring all connections are secure.
Torque the mounting bolts to the manufacturer's specifications.

4. Inspect and Replace Steering Components (if necessary)

If the power steering pump is functioning correctly, inspect the steering rack and tie rods.
Replace any worn or damaged components as needed.
Reassemble any components removed during the inspection.
