Remove the front axle differential oil with the specifications stated above and then remove the left drive axle then the right drive axle from the bearing pedestal, leave it to extend for 7 to 8 cm. Then, you should take out the front drive shaft, then unbolt and lower the differential paying a lot of attention to avoid dropping it. Before reinstalling the differential, replace the sealing O-ring between the oil pan and differential by installing a new one and coating a 1/4 inch of the inside edge with front differential oil. Return the differential to the oil pan, but do not forget the drive axle flange seal before fitting the drive axle; examine the differential oil level.
