Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Differential fluid pump
- Oil catch pan
- Safety goggles and gloves
Safety Warnings:
- Ensure the vehicle is on a flat, stable surface.
- Use jack stands to support the vehicle securely.

2. Drain Differential Fluid

Place an oil catch pan under the differential.
Locate the differential drain plug and remove it using the appropriate socket.
Allow the fluid to completely drain out into the catch pan.

3. Inspect Gears and Bearings

Remove the differential cover by unscrewing the bolts using a socket.
Carefully take off the cover and inspect the gears and bearings for signs of wear or damage (chips, pitting, or discoloration).
Check the condition of the ring and pinion gears. If damaged, replacement is necessary.

4. Replace Damaged Components

If any gears or bearings are damaged, remove them carefully.
Install new bearings and gears according to manufacturer specifications.
Apply assembly lube to new components to ensure proper operation.

5. Reassemble and Refill

Reinstall the differential cover and torque the bolts to the manufacturer’s specifications.
Use the differential fluid pump to fill the differential with the appropriate fluid type until it reaches the fill hole.
Replace the fill plug and ensure it is sealed properly.

6. Final Checks

Lower the vehicle from the jack stands.
Start the engine and allow the differential to operate for a few minutes.
Check for any leaks around the differential cover and plugs.
