Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, oil catch pan, differential fluid, gear oil pump, OBD-II scanner.
Safety Warnings: Ensure the vehicle is on a level surface and secured with jack stands before working underneath.

2. Fluid Replacement

Drain Old Fluid:
- Position the oil catch pan under the differential.
- Remove the drain plug using a socket wrench and allow the fluid to completely drain.
Inspect Drain Plug:
- Check the drain plug for metal shavings or debris. Clean it if necessary.
Replace with New Fluid:
- Install the drain plug and torque it to the manufacturer’s specifications (typically around 30-40 lb-ft).
- Use a gear oil pump to fill the differential with the recommended fluid until it reaches the fill hole.
- Replace the fill plug and torque it to specifications.

3. Inspect and Replace Components

Inspect Differential Gears:
- If noise persists after fluid replacement, remove the differential cover to inspect the gears and bearings for wear.
- Replace any damaged components such as gears or bearings, ensuring proper alignment and lubrication.
Check and Replace Mounts:
- If mounts or bushings are damaged, remove them and install new ones. Ensure they are torqued to specification.

4. Reassemble and Test

Reassemble Differential Cover:
- If removed, clean the mating surfaces and apply new gasket material or sealant.
- Torque cover bolts to the specified value (typically 15-20 lb-ft).
Test Drive the Vehicle:
- After reassembly, take the car for a test drive to confirm that the noise has been resolved.
