Solution

1. Preparation

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

2. Drain Differential Fluid

Tools Required: Socket set, drain pan
Place a drain pan under the differential.
Remove the differential drain plug using a socket.
Allow the fluid to completely drain out.

3. Inspect and Replace Differential Components

Tools Required: Torque wrench, bearing puller, seal puller
Remove the differential cover using a socket set.
Inspect the ring and pinion gears for wear or damage.
Check bearings for signs of wear or damage; replace if necessary.
- If the bearings are damaged, use a bearing puller to remove and replace them.
If gears are damaged, replace with OEM or high-quality aftermarket parts.

4. Clean and Reassemble

Clean the differential housing and cover with a suitable cleaner.
Apply a new gasket or silicone sealant to the differential cover.
Reinstall the differential cover and torque bolts to manufacturer specifications (usually around 30-40 Nm).

5. Fill Differential with New Fluid

Parts Required: Differential fluid (consult owner’s manual for specifications)
Insert a funnel into the fill hole and pour the new differential fluid until it reaches the fill level.

6. Test Drive

Reconnect the battery terminal.
Test drive the vehicle to ensure that the noise has been resolved and that the differential operates smoothly.
