Inspect the fluid for metal shavings or debris, indicating internal damage.

3. Inspect and Replace Differential Components

Tools Required: Socket set, pry bar, torque wrench
Remove the differential cover by unscrewing the bolts with the socket set.
Inspect the gears, bearings, and seals for wear, damage, or excessive play.
If damage is found, replace the affected components, including bearings or seals.
Reassemble the differential cover and torque to manufacturer specifications.

4. Refill Differential Fluid

Tools Required: Funnel
Use a funnel to refill the differential with fresh fluid, ensuring it meets the manufacturer's specifications.
Replace the drain plug and torque it to the specified value.
