Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, jack and jack stands, multimeter, and torque wrench.
  • Ensure the vehicle is on a level surface and the engine is turned off.
2. Inspect and Replace Serpentine Belt
  • Inspect the belt for wear or damage.
    • If damaged, proceed to replace it.
  • Remove the serpentine belt:
    • Loosen the tensioner pulley using a socket and ratchet.
    • Slip the belt off the pulleys.
  • Install the new serpentine belt:
    • Route the new belt according to the belt routing diagram.
    • Ensure the belt is seated correctly on all pulleys.
    • Reapply tension using the tensioner pulley.
3. Check and Top Off Fluid Levels
  • Transmission Fluid:
    • Locate the transmission dipstick.
    • Pull the dipstick, wipe it clean, and reinsert to check the level.
    • If low, add the appropriate transmission fluid as specified in the owner's manual.
  • Differential Fluid:
    • Check the differential fluid level using the fill plug.
    • If low, add the manufacturer-recommended gear oil until it starts to seep from the fill hole.
4. Inspect Wheel Bearings and CV Joints
  • Lift the front of the vehicle using a jack and secure with jack stands.
  • Check for play in the wheel bearings:
    • Grab the wheel at 12 and 6 o'clock positions and shake; any movement indicates bearing wear.
  • Inspect CV joints for any grease leakage or cracks in the rubber boots.
5. Inspect Power Steering System
  • Check power steering fluid level in the reservoir.
  • Listen to the power steering pump while the engine is running for any unusual noises.
  • If noise persists, consider replacing the power steering pump.
