Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Drain Differential Fluid

Tools Required: Socket set, container for fluid.
Place a container underneath the differential.
Remove the drain plug and allow the fluid to completely drain.
Inspect the fluid for metallic particles or contamination.

3. Replace Differential Fluid

Tools Required: Funnel, new differential fluid (refer to the owner's manual for specifications).
Replace the drain plug and torque it to manufacturer specifications.
Use a funnel to refill the differential with the appropriate fluid until it reaches the fill plug.

4. Inspect and Replace Damaged Components

Tools Required: Socket set, torque wrench.
Remove the differential cover if internal inspection is needed.
Inspect gears, bearings, and seals for wear or damage.
Replace any worn components using manufacturer-recommended parts, ensuring proper torque specifications during reassembly.

5. Reassemble Differential

Reattach the differential cover if it was removed.
Use a new gasket or sealant as necessary.
Reinstall the fill plug and torque it to specifications.
