Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a flat surface and engage the parking brake.
  • Disconnect the battery to ensure safety.
2. Check Power Steering System
  • Sub-steps:
    1. Locate the power steering reservoir and check the fluid level.
    2. If low, top off with the manufacturer-recommended power steering fluid.
    3. Inspect hoses for leaks or cracks and replace if necessary.
3. Inspect Serpentine Belt
  • Sub-steps:
    1. Remove the engine cover if applicable.
    2. Visually inspect the serpentine belt for signs of wear or damage.
    3. Use a belt tension gauge to check tension; replace if out of specification.
    4. If damaged, remove the old belt using a socket set and install a new one.
4. Inspect Wheel Bearings
  • Sub-steps:
    1. Raise the vehicle using a jack and secure with jack stands.
    2. Remove the wheel to access the hub assembly.
    3. Check for play by moving the wheel back and forth; replace the bearing if necessary.
    4. Reassemble the wheel and lower the vehicle.
5. Check Transmission Fluid
