Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Drain Differential Fluid

Tools Required: Socket set, drain pan
Using a socket, remove the differential drain plug and allow the old fluid to drain completely into the pan.
Inspect the old fluid for metal shavings or debris, which indicates internal damage.

3. Replace Differential Fluid

Tools Required: Funnel, new differential fluid (check owner’s manual for specifications)
Replace the drain plug with a new gasket if necessary and tighten to manufacturer specifications (usually around 30 Nm).
Use a funnel to refill the differential with new fluid until it reaches the fill level specified in the owner’s manual.

4. Inspect and Replace Components

Tools Required: Socket set, torque wrench
If noise persists, remove the differential cover and inspect the gears and bearings for wear.
Replace any damaged components such as bearings or gears, ensuring to torque all bolts to manufacturer specifications.

5. Reassemble and Test

Reattach the differential cover and refill with new fluid as described in step 3.
Reconnect the battery and perform a test drive to ensure the noise is resolved.
