Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Differential Fluid

Drain the Old Fluid:
- Place a drain pan under the differential.
- Remove the drain plug using a socket wrench and allow fluid to completely drain.
- Clean the drain plug and replace the washer if damaged.
Inspect Fluid Condition:
- Check the drained fluid for metal shavings or a burnt smell, indicating internal damage.
Refill with New Fluid:
- Replace the drain plug and torque to manufacturer specifications.
- Remove the fill plug and use a funnel to add the recommended differential fluid (check owner’s manual for specifications).
- Replace the fill plug and torque it to specifications.

3. Inspect for Mechanical Damage

Remove Differential Cover:
- If noise persists, remove the differential cover (if applicable) by unscrewing the bolts.
- Inspect the internal components for wear, cracks, or metal debris.
Check Bearings and Gears:
- Rotate the differential gears by hand to feel for roughness or binding.
- Replace any damaged bearings or gears as needed.
Reassemble Differential:
- Clean the mating surfaces and apply new gasket material or replace the gasket.
- Reinstall the differential cover and torque bolts to specification.
