Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Differential fluid pump
Safety Warnings:
- Ensure the vehicle is on a level surface and secured with jack stands.
- Allow the vehicle to cool before working on the differential.

2. Fluid Change

Raise the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
Drain Old Fluid: Locate the differential drain plug, remove it, and let the old fluid drain completely into a pan.
Inspect Drain Plug: Check the drain plug for metal shavings or debris, which indicates internal wear.
Replace Fluid: Use a differential fluid pump to fill the differential with the recommended fluid until it reaches the fill hole.
Reinstall Drain Plug: Torque the drain plug to the manufacturer’s specification.

3. Inspect and Replace Components

Remove Differential Cover: If necessary, remove the differential cover for a detailed inspection.
- Use a socket set to remove the bolts.
Inspect Internal Components: Check gears, bearings, and seals for wear or damage.
Replace Worn Components: If any components are worn or damaged, replace them with OEM parts.
Reassemble Differential: Clean the mating surfaces, apply new gasket or sealant, and reinstall the differential cover.
