Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted with jack stands.
Wear safety glasses and gloves for protection.

2. Drain Differential Fluid

Locate the differential drain plug.
Use a socket wrench to remove the drain plug and allow the fluid to fully drain into a suitable container.
Inspect the old fluid for metal shavings or excessive debris.

3. Inspect and Clean Components

Remove the differential cover if necessary for a thorough inspection.
Clean the differential housing surfaces and remove any old gasket material.
Inspect the gears and bearings for signs of wear or damage.

4. Replace Differential Fluid

Reinstall the drain plug and torque it to the manufacturer’s specifications.
Fill the differential with the recommended type and amount of fluid (typically 75W-90 gear oil).
Reinstall the fill plug and ensure it is secured.

5. Reassemble and Test

If the differential cover was removed, replace the gasket or use sealant and reattach it.
Lower the vehicle and conduct a test drive to monitor for any remaining noise or issues.
