Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the manufacturer-recommended power steering fluid if low.
Inspect the fluid for contamination (milky appearance or debris).

3. Inspect and Replace Leaking Components

Tools Required: Wrench set, socket set, power steering fluid
Identify any leaks from hoses or the power steering pump:
- If hoses are damaged, disconnect them using the appropriate wrench and replace with OEM parts.
- If the power steering pump is leaking, detach the pump by removing the mounting bolts and disconnecting the hoses.
Install the new power steering pump or hoses, ensuring all connections are tight and secure.

4. Bleed the Power Steering System

Reconnect all components and refill the power steering fluid to the appropriate level.
Start the engine and turn the steering wheel from lock to lock several times to purge air from the system.
Check fluid levels again and top off as necessary.

5. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Test drive the vehicle to confirm that steering effort is normal and listen for any unusual noises.
