Solution

1. Preparation

Gather tools: jack stands, socket set, torque wrench, transmission fluid, differential fluid, and cleaning cloths.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Transmission Fluid

Remove the transmission dipstick, wipe it clean, and reinsert it to check the fluid level.
If low, add the recommended transmission fluid until it reaches the proper level.
If dirty or burnt, perform a transmission fluid change.

3. Check Serpentine Belt and Pulleys

Visually inspect the serpentine belt for cracks, fraying, or glazing.
If damaged, replace the serpentine belt using a socket set to relieve tension on the tensioner.
Inspect the pulleys for wear; replace any damaged or worn components.

4. Inspect Differential Fluid

Remove the differential fill plug and check fluid level; it should be at the bottom of the hole.
If low, add the specified differential fluid until it reaches the fill hole.
If the fluid is dark or contains debris, drain and replace the differential fluid.

5. Inspect Wheel Bearings and CV Joints

Lift the vehicle and remove the wheels to access the wheel bearings and CV joints.
Rotate the hub; listen for noise indicating bearing wear. Replace if necessary.
Inspect CV joints for any tears in the boots or excessive play; replace if damaged.
