The rear blocks are sitting on the axle perch and the springs on top of them, it'll all separate when you get it up in the breeze, cut the u-bolts off, and lower the rear axle. You'll have to check the drive shafts to make sure they haven't been lengthened, I'm not sure if they have to be lengthened for a 4" lift or not but they do need to be checked.
