Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, jack and jack stands, socket set, torque wrench, transmission fluid.
Safety Warning: Ensure the vehicle is on a flat surface and use jack stands to secure it before working underneath.

2. Inspect and Replace Drive Belts

Sub-steps:
1. Remove the engine cover (if applicable) using the socket set.
2. Visually inspect the serpentine belt for cracks, fraying, or glazing.
3. If damaged, loosen the tensioner and remove the old belt.
4. Install a new serpentine belt, ensuring it follows the correct routing.
5. Tighten the tensioner to specification (usually around 15-20 ft-lbs).

3. Check and Change Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick or fill plug.
2. Remove the dipstick to check fluid level; add fluid if low (use manufacturer-recommended fluid).
3. If fluid is burnt, drain and replace with new fluid.
4. Use a fluid pump to fill the transmission until it reaches the proper level.

4. Replace Worn Wheel Bearings (if necessary)

Sub-steps:
1. Remove the wheel and tire assembly.
2. Detach the brake caliper and rotor to access the wheel hub.
3. Remove the hub assembly using a socket set, and note the torque specifications for reinstallation.
4. Press out the old bearing and press in the new bearing.
5. Reassemble the hub, rotors, and calipers, tightening the bolts to specified torque.
