Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, with the engine off and keys removed.
Raise the vehicle using a jack and secure it with jack stands.

2. Drain Differential Fluid

Tools Required: Drain pan, socket set, torque wrench.
Place a drain pan underneath the differential.
Remove the differential drain plug using a socket wrench.
Allow the fluid to drain completely, then replace the drain plug and torque to manufacturer's specifications.

3. Inspect and Replace Differential Fluid

Tools Required: Funnel, new differential fluid as specified by the manufacturer.
Remove the fill plug from the differential.
Use a funnel to refill the differential with new fluid until it reaches the fill level.
Replace the fill plug and torque to specifications.

4. Inspect Differential Components

Tools Required: Socket set, pry bar, inspection mirror.
Remove the differential cover if necessary to inspect internal components.
Check for wear or damage on gears, bearings, and seals.
Replace any worn or damaged components as needed, ensuring proper alignment and lubrication.

5. Reassemble and Lower Vehicle

Replace the differential cover with a new gasket if removed.
Torque the cover bolts to specifications.
Remove jack stands and lower the vehicle carefully.
