Safety Warning: Ensure the vehicle is securely supported on jack stands.

3. Inspect and Replace Components

Sub-steps:
1. Remove the differential cover if it is accessible and inspect the gears for wear or damage.
2. Check the bearings for smooth operation; replace if they feel rough or gritty.
3. Replace any worn or damaged components, including seals and gaskets, ensuring to clean the mating surfaces before reassembly.
4. Reinstall the differential cover and tighten bolts to the manufacturer's torque specifications.
Tools Required: Gasket scraper, sealant, torque wrench.

4. Reassemble and Refill

Sub-steps:
1. Reinstall the differential fill plug securely.
2. Reconnect the battery.
3. Start the vehicle and let it run for a few minutes to circulate the fluid.
4. Check for any leaks around the differential area.
