Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, stethoscope (optional).
Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Inspect Serpentine Belt

Sub-steps:
1. Open the hood and visually inspect the serpentine belt for cracks or fraying.
2. If damaged, use a socket set to remove the tensioner and take off the belt.
3. Replace the serpentine belt with a new one and ensure proper routing.

3. Check Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (if applicable) and remove it.
2. Wipe it clean, reinsert, and then pull it out again to check fluid level.
3. If low, add the appropriate type of transmission fluid as specified in the owner’s manual. If dirty, consider a fluid change.

4. Inspect Wheel Bearings and CV Joints

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Spin each wheel by hand to listen for grinding noises indicating bad bearings.
3. Check for play in the CV joints by moving the axle in and out while observing for any excessive movement.
4. Replace any damaged wheel bearings or CV joints as necessary.

5. Reassemble and Check

After inspecting and replacing components, reassemble any parts removed.
Ensure all tools are accounted for and the work area is clear.
