Solution

1. Preparation

Gather tools: jack, jack stands, wrench set, differential fluid, and a drain pan.
Ensure the vehicle is parked on a flat surface and the engine is off.
Safety Warning: Disconnect the battery before starting work on the vehicle.

2. Raise the Vehicle

Use a jack to lift the truck and secure it on jack stands.
Make sure the vehicle is stable before proceeding.

3. Inspect and Drain Differential

Locate the differential cover and inspect for any cracks or damage.
Place a drain pan under the differential and remove the drain plug or cover bolts.
Allow the old fluid to drain completely into the pan.

4. Clean and Replace Components

Clean the differential cover and mating surfaces to ensure a proper seal.
Replace the gasket or use sealant as required.
If necessary, replace any damaged components such as bearings or gears within the differential.

5. Refill Differential

Fill the differential with the manufacturer's recommended fluid type and quantity (check the owner's manual for specifications).
Reinstall the drain plug or cover and torque it to the specified value (typically around 30-40 ft-lbs, but verify in the manual).

6. Final Checks

Lower the vehicle off the jack stands.
Reconnect the battery.
Test drive the vehicle to ensure proper function and check for any leaks.
