2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir.
2. Check the fluid level and condition. If the fluid is dark or contains debris, proceed to replace it.
3. Using a turkey baster or suction tool, remove old fluid from the reservoir.

5. Start the engine and turn the steering wheel from lock to lock to bleed the system.

3. Replace Worn Steering or Suspension Components

Sub-steps:
1. Remove the wheel to access the suspension and steering components.
2. Inspect the tie rod ends, control arms, and bushings for excessive wear or damage.
3. If any components are found to be worn, use a socket set to remove the damaged part.
4. Install the new component, ensuring all bolts are torqued to manufacturer specifications.
5. Reinstall the wheel and lower the vehicle.

4. Inspect and Replace Wheel Bearings or CV Joints

Sub-steps:
1. With the vehicle lifted, spin each wheel to listen for grinding noises.
2. If a wheel bearing is suspected, remove the wheel and brake assembly.
3. Use a socket set to remove the bearing hub assembly if necessary.
4. Replace the bearing with a new one and ensure it is properly lubricated.
5. Reassemble the brake assembly and wheel, and lower the vehicle.
