Solution

1. Preparation

Gather tools: jack, jack stands, wrench set, fluid catch pan, and a flashlight.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Fluid Inspection

Remove the differential fill plug: Use the appropriate wrench to loosen and remove the fill plug.
Check fluid level: Fluid should be at the level of the fill hole. If low, add the recommended differential fluid (usually 75W-90).
Inspect fluid condition: Look for any signs of contamination or metal shavings. If the fluid is dark or has debris, it indicates potential internal damage.

3. Visual Inspection

Lift the vehicle: Use a jack to lift the rear of the vehicle securely and place jack stands underneath.
Inspect the differential: Look for cracks, leaks, and overall damage on the differential housing.
Check the driveshaft: Inspect for play in the driveshaft and differential output shafts by attempting to move them in and out.

4. Noise and Vibration Diagnosis

Test drive: Conduct a test drive at various speeds and turning conditions to replicate any noises or vibrations.
Listen for sounds: Pay attention to any whining, grinding, or clunking noises, especially when turning or accelerating.

5. Replacement (if necessary)

Drain the differential fluid: Place a fluid catch pan under the differential and remove the drain plug.
Remove the differential: If replacing, disconnect the driveshaft and remove bolts securing the differential to the chassis. Carefully lower it.
Install new differential: Position the new or rebuilt differential, secure it with bolts, and reconnect the driveshaft.
Replenish differential fluid: Refill with the appropriate fluid through the fill hole until it reaches the correct level.
