Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during work.

2. Drain Differential Fluid

Tools Required: Drain pan, socket set, torque wrench.
Place the drain pan underneath the differential.
Remove the drain plug and allow the old fluid to completely drain out.
Inspect the fluid for metal shavings or debris.

3. Inspect and Replace Differential Components

Tools Required: Socket set, pry bar, torque wrench.
Remove any necessary covers to access the differential gears.
Inspect the gears for wear or damage; replace if necessary.
Replace any worn bearings or seals as needed. Ensure all components are correctly lubricated.

4. Refill Differential with New Fluid

Tools Required: Funnel.
Use a funnel to refill the differential with manufacturer-recommended fluid to the proper level.
Replace the drain plug and tighten it to the specified torque.

5. Reassemble and Test

Reattach any covers previously removed.
Reconnect the battery.
Perform a test drive to ensure all issues have been resolved.
