After lifting my van and using aftermarket torsion bar keys, the inner CV joint angles were quite severe and causing the CV joint boots to destroy themselves over time. So I decided to lower the front axle 13/4" to lessen the angle of the CV shafts. This also gave better clearance between the right side axle tube and the oil pan. Here's some pics of how I accomplished this.
