Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, OBD-II scanner, socket set, torque wrench, fluid catch pan.
Ensure the vehicle is parked on a level surface and engine is off. Disconnect the battery for safety.

2. Inspect and Replace Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the transmission and differential drain plugs.
3. Remove the drain plugs and allow old fluid to drain into a fluid catch pan.
4. Inspect the fluid for metal shavings or burning smell; if present, further investigation is needed.
5. Reinstall the drain plugs and fill with new fluid as recommended in the owner's manual, ensuring proper fluid type and level.

3. Check Drive Belts and Pulleys

Sub-steps:
1. Visually inspect all drive belts for cracks or fraying.
2. Check the tensioner and idler pulleys for smooth operation; replace if seized or noisy.
3. If any belts are worn, remove them using the appropriate socket set and replace with new OEM belts.

4. Wheel Bearing Inspection

Sub-steps:
1. With the vehicle still elevated, grab each wheel and check for excessive play by moving it side to side.
2. Spin the wheel to listen for grinding noises; if present, replace the bearing.
3. Remove the wheel and brake caliper to access the hub assembly, then replace the bearing as necessary.
