Solution

1. Preparation

Gather tools and materials. Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Tools Required: Jack and jack stands, torque wrench, OBD-II scanner, basic hand tools (sockets, wrenches), flashlight.

2. Inspect Serpentine Belt

Sub-steps:
1. Open the hood and visually inspect the serpentine belt for cracks, fraying, or signs of wear.
2. If damage is evident, remove the belt by releasing tension using a belt tensioner tool.
3. Replace with a new serpentine belt of the correct specifications.
Safety Warning: Ensure the engine is off and cool before working on the belt.

3. Check Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe it clean, reinsert, and remove again to check fluid level.
3. If low, add manufacturer-recommended transmission fluid.
4. If the fluid is dark or has a burnt smell, consider a transmission fluid change.
Safety Warning: Be cautious of hot engine components if the engine has been running.

4. Inspect Wheel Bearings and CV Joints

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Spin each wheel by hand and listen for noise or roughness.
3. Grab the wheel at 12 and 6 o'clock positions and rock it. If there is excessive play, consider replacing the wheel bearing.
4. Inspect the CV joints for torn boots or grease leaks; replace if necessary.
