Solution

1. Preparation

Tools Required: Jack and jack stands, OBD-II scanner, socket set, torque wrench, fluid catch pan.
Ensure the vehicle is on a level surface and secure it with jack stands.

2. Fluid Check and Replacement

Engine Oil Check:
- Remove the dipstick, wipe it clean, reinsert, and check oil level.
- If low, top off with manufacturer-recommended oil type.
Transmission Fluid Check:
- Follow the manufacturer’s procedure for checking fluid level (usually requires the engine running).
- If fluid is low or dirty, drain and replace with the correct type and amount.
Differential Fluid Check:
- Remove the fill plug and check fluid level.
- If low, drain the old fluid and refill with manufacturer-recommended differential fluid.

3. Belt and Pulley Inspection

Visual Inspection:
- Check for cracks, fraying, or glazing on the serpentine belt.
- Ensure pulleys spin freely without wobbling or noise.
Replacement:
- If damaged, remove the old belt using a socket to release tension and install a new belt.

4. Wheel Bearing Inspection

Jack Up Vehicle:
- Securely elevate the vehicle and remove the wheel.
Spin Wheel:
- Rotate the wheel by hand; listen for grinding or roughness indicating a bad bearing.
Replacement:
- If needed, press out the old bearing and press in a new bearing using a bearing tool.

5. Differential Inspection

Check for Leaks:
- Inspect around the differential for fluid leaks.
Internal Inspection:
- If leaking or damaged, remove the differential cover, inspect gears and bearings, replace as necessary.
