Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted on jack stands.
Wear safety gloves and goggles.

2. Drain Differential Fluid

Tools Required: Socket set, fluid catch pan.
Locate the differential drain plug and remove it using the socket set.
Allow the old fluid to completely drain into the catch pan.

3. Inspect Differential Components

Remove the differential cover using the socket set.
Inspect the gears, bearings, and seals for any signs of wear or damage.
Check for metal shavings or debris in the fluid.

4. Replace Damaged Components

If any components (bearings, seals, or gears) are damaged, replace them with OEM parts.
Ensure all parts are cleaned before installation.

5. Reassemble and Refill Differential

Replace the differential cover and torque the bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Fill the differential with new fluid (check the owner’s manual for the correct type, typically 75W-90 gear oil) until it reaches the fill hole.
