Tools Required: Drain pan, socket set
Place the drain pan under the differential.
Remove the differential drain plug using the appropriate socket.
Allow the fluid to completely drain into the pan.

3. Inspect Differential Components

Tools Required: Socket set, torque wrench
Remove the differential cover using a socket set.
Inspect the gears, bearings, and shims for wear or damage.
Check the condition of the differential housing for cracks or irregularities.

4. Replace Worn Components

If any gears or bearings are damaged, replace them with OEM or high-quality aftermarket parts.
Ensure that the new components are installed according to manufacturer specifications, including proper torque values.

5. Clean and Reassemble

Clean the differential cover and mating surfaces thoroughly.
Apply a new gasket or RTV sealant as recommended by the manufacturer.
Reinstall the differential cover and tighten the bolts to the specified torque.

6. Refill Differential Fluid

Tools Required: Funnel, new differential fluid
Refill the differential with the recommended fluid type using a funnel.
Replace the differential drain plug and tighten to specification.
