I had a Grand Cherokee 2 wheel drive back in the 90's. Found out the Differental in it had an aluminm pumpkin - center section -. I jacked up the back end using the pumpkin - bad move - beeing aluminum it bent and now the gears were constantly spinning, whirring noise. Got a rebuilt differential for $1200
Try a maginet on the pumpkin case and see if it sticks, if it dosen't it's aluminum. Watch the tire shops as they use the jack under the pumpkin a lot. Even now I never jack up using the pumpkin or let shops do it, it was not designed as a jack point - the weight of the car is on the springs and wheels on the ends of the axle assembly.
