To change the differential oil on a 2007 Jeep Commander, first ensure the vehicle is on a level surface and safely supported on jack stands. Remove the differential cover bolts and carefully take off the cover, allowing the old oil to drain completely. Clean the mating surfaces, replace the gasket, and refill the differential with the appropriate oil, typically 75W-140 for the rear and 75W-90 for the front, until it reaches the fill hole. Finally, reattach the cover, tighten the bolts, and dispose of the old oil properly.
