Solution

1. Preparation

Tools Required:
- Phillips screwdriver
- Socket set
- Funnel
- Clean rags
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Access the Power Steering Fluid Reservoir

Locate the power steering fluid reservoir. It is usually situated near the engine bay.
Remove any covers or components obstructing access to the reservoir.

3. Bleed the Power Steering System

Sub-steps:
1. Fill the power steering reservoir with the recommended fluid type (consult owner's manual for specifications).
2. Start the engine and let it idle.
3. Turn the steering wheel from lock to lock slowly for about 10-15 cycles. This allows the fluid to circulate and push out air.
4. Monitor the fluid level in the reservoir; add more fluid if necessary to prevent it from running low.
5. After cycling the steering, turn off the engine and check for any air bubbles in the reservoir.
6. If bubbles are present, repeat the lock-to-lock procedure as needed.

4. Final Check

After bleeding, check the fluid level one last time and top off if needed.
Reconnect the battery and start the engine to ensure normal operation.
Test drive the vehicle to ensure proper steering function.
