Solution

1. Preparation

Gather tools: socket set, torque wrench, power steering fluid, OBD-II scanner.
Park the vehicle on a level surface and ensure the ignition is off.
Disconnect the battery to avoid any electrical issues during the repair.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, add the appropriate type of fluid (check owner's manual for specifications).
Start the engine and turn the wheel from lock to lock to circulate the fluid, then recheck the level.

3. Inspect Power Steering System Components

Visually inspect the power steering hoses for cracks or leaks.
Check the power steering pump for any signs of failure (whining noises or leaks).
If the pump is faulty, replace it by:
1. Detaching the hoses from the pump (ensure to collect any fluid).
2. Remove the pump mounting bolts.
3. Install the new pump, tightening bolts to manufacturer's specifications (usually around 20-25 ft-lbs).

4. Inspect Steering Rack

Check the steering rack for leaks or signs of wear.
If replacement is necessary:
1. Disconnect the battery and remove the front wheels for easier access.
2. Disconnect the steering linkage from the rack.
3. Remove the mounting bolts and carefully extract the rack.
4. Install the new rack, ensuring it's properly aligned and secured.

5. Reassemble and Test

Reconnect any components that were detached during the inspection and repair.
Refill the power steering fluid to the correct level and bleed the system by turning the steering wheel from lock to lock.
Reconnect the battery and start the vehicle.
