Solution
1. Preparation
  • Gather tools and materials.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Safety warning: Allow the engine to cool before servicing.
2. Fluid Inspection
  • Transmission Fluid:

    • Locate the transmission dipstick.
    • Remove and wipe the dipstick clean, then reinsert and check the fluid level.
    • If low, add the correct type of transmission fluid as specified in the owner's manual.
  • Differential Fluid:

    • Locate the differential fill plug.
    • Remove the plug and check fluid level; it should be at or near the bottom of the fill hole.
    • If low, add the appropriate differential fluid.
3. Belt Inspection and Replacement
  • Inspect Serpentine Belt:
    • Visually check for fraying, cracking, or excessive wear.
    • If damaged, remove the belt by releasing tension from the tensioner pulley.
    • Install a new serpentine belt, ensuring correct routing.
4. CV Joint and Axle Inspection
  • Inspect CV Joints:
    • Raise the vehicle using a jack and secure it with jack stands.
    • Inspect CV boots for any tears or leaks.
    • If the CV joint is damaged, remove the axle shaft and replace the joint or the entire axle as necessary.
5. Test Drive
  • After completing repairs, start the vehicle and take it for a test drive to verify the noise has been eliminated.
