Solution

1. Preparation

Gather tools: socket set, OBD-II scanner, jack and jack stands, safety glasses, and torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Belts

Sub-steps:
1. Open the hood and visually inspect all belts (serpentine and accessory belts) for wear, cracks, or fraying.
2. If any belts are damaged, loosen the tensioner using a socket wrench and remove the old belt.
3. Install the new belt by routing it according to the belt routing diagram, ensuring it is seated properly on all pulleys.
4. Tighten the tensioner to secure the new belt.

3. Check and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the transmission filler/dipstick tube and remove the dipstick.
3. Check the fluid level and condition; if low, drain the old fluid from the transmission pan.
4. Replace the transmission fluid with the manufacturer-recommended type, filling it to the proper level.
5. Reattach the dipstick and lower the vehicle.

4. Inspect Drive Shaft and Differential

Sub-steps:
1. Visually inspect the drive shaft for any signs of damage, such as dents or excessive rust.
2. Check the universal joints for play or binding; replace if necessary.
3. Inspect the differential fluid level and condition, adding fluid as needed.
4. If any components are damaged, replace them according to the manufacturer’s specifications.
