Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Tools Required: Jack and jack stands, socket set, OBD-II scanner, multimeter (if needed).

2. Check and Replace Belts

Inspect the serpentine belt for cracks or signs of wear.
- If damaged, use a socket set to remove the tensioner and replace the belt.
Check the drive belt tension and adjust if necessary.
- Use a torque wrench to ensure proper tension as specified in the service manual.

3. Inspect and Replace Fluid

Check the transmission fluid level:
- With the engine running, remove the dipstick, wipe it clean, and reinsert it to check the level.
- If low, add the appropriate transmission fluid as specified in the owner's manual.
Check the power steering fluid level:
- Inspect the reservoir and top off with the recommended fluid if necessary.

4. Inspect Wheel Bearings and Differential

Raise the vehicle on jack stands and remove the wheels.
Spin the wheel hubs to check for roughness or noise indicative of bad bearings.
- If noise is present, replace the wheel bearings using a bearing puller and follow with a proper installation procedure.
Inspect the differential fluid:
- If applicable, check the level and condition of the differential fluid. Replace if dirty or low.
