Lowering diff...help

[mbtjc]

I am in the middle of replacing my rear subframe bushings and differential mount. While I am doing all this, I want to take off the differential cover and reseal it since it is weeping. Since the upper 2 bolts for the differential cover are concealed by the frame crossmember, I thought this would be a great time to do this since taking off the diff mount lowers the diff...to get the the bolts, and the nut strip inside the frame for the diff mount. I let down the diff (limited slip) all the way, and it lowered it a good 1.5-2 inches, but it still needs to go down about another inch before I can get to the upper 2 bolts. How do I get the diff to go down another inch or so? Any help is appreciated. Thanks!
