Solution

1. Preparation

Gather tools and parts: Ensure you have all necessary tools and replacement parts ready.
Safety measures: Disconnect the battery before starting work on the vehicle.
Lift the vehicle: Use a jack to elevate the car and secure it with jack stands for safety.

2. Inspect and Replace Differential Fluid

Drain old fluid: Remove the differential drain plug and allow the fluid to completely drain into a suitable container.
Inspect fluid: Check for metal shavings or discoloration that may indicate internal damage.
Replace with new fluid: Referring to the owner’s manual, refill the differential with the recommended type of gear oil (typically 75W-90 or as specified).

3. Inspect Differential Components

Remove differential cover: If noise persists, remove the differential cover by unbolting it and gently prying it off.
Inspect gears and bearings: Check for wear on differential gears and bearings. Look for scoring, pitting, or abnormal wear patterns.
Replace damaged components: If any components are worn or damaged, replace them with OEM or high-quality aftermarket parts.

4. Reassemble and Test

Reinstall cover: Clean the mating surfaces and apply a new gasket or sealant as necessary, then reinstall the differential cover.
Torque specifications: Ensure all bolts are tightened to the manufacturer’s torque specifications.
Refill differential fluid: Make sure to refill with the correct amount of new fluid.
