Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the appropriate power steering fluid if low.
Inspect fluid for contamination or burning smell, which may indicate pump failure.

3. Inspect and Replace Power Steering Pump (if needed)

Disconnect the negative battery terminal to prevent electrical shorts.
Remove the drive belt from the power steering pump using a socket set.
Unplug the power steering pump electrical connector.
Remove the bolts securing the pump to the engine and take out the pump.
Replace with a new pump, ensuring proper alignment of the mounting holes.
Reinstall the drive belt and reconnect the electrical connector.

4. Inspect Steering Rack and Tie Rods

Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the steering rack for any visible damage or leaks.
Check tie rod ends for play or damage; replace if necessary.
Ensure all connections are tight and secure.

5. Test and Reassemble

Lower the vehicle and reconnect the negative battery terminal.
Start the engine and turn the steering wheel from lock to lock to bleed the system.
Check for any abnormal noises after the repair.
Recheck the power steering fluid level and top off if necessary.
