Solution

1. Preparation

Tools Required: Socket set, wrench, clean rag, funnel, and a container for fluid if needed.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Fluid Replacement (if necessary)

Drain Old Fluid:
- Position a drain pan under the differential to catch the old fluid.
- Remove the drain plug using a socket or wrench and allow the fluid to completely drain out.
- Clean the drain plug and inspect for metal shavings or debris.
Replace with New Fluid:
- Reinstall the drain plug and torque it to the manufacturer's specifications (usually around 30-40 ft-lbs).
- Using a funnel, fill the differential with a suitable fluid type (typically 75W-140 synthetic gear oil for Ford Explorers). Fill until the fluid begins to seep out of the fill hole.
Reinstall Fill Plug:
- Once filled, reinstall the fill plug and torque it to the manufacturer's specifications (around 20-25 ft-lbs).

3. Clean Up

Wipe any spilled fluid and properly dispose of the old fluid according to local regulations.
