Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, and OBD-II scanner.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; if low, top it off with the manufacturer-recommended fluid.
If the fluid is discolored or contaminated, drain and replace it:
1. Disconnect the return line from the reservoir.
2. Use a siphon pump to remove old fluid.
3. Reconnect the return line and fill with new fluid.
4. Start the engine and turn the steering wheel to circulate fluid.

3. Inspect Steering Components

Remove the front wheels using a socket set.
Visually inspect tie rods and control arms for any damage or excessive wear.
Replace components if any play or damage is found:
1. Use a wrench to remove the nuts securing the component.
2. Replace with new parts and torque to manufacturer specifications.

4. Check and Replace Wheel Bearings

With the vehicle raised, spin each wheel by hand to check for noise.
If noise is present, remove the wheel and inspect the bearing:
1. Use a socket set to remove the hub assembly.
2. Replace with a new bearing and reassemble, ensuring proper torque specs are followed.

5. Final Assembly

Reinstall the wheels and lower the vehicle.
Reconnect the battery.
Clear any error codes using the OBD-II scanner.
