Throw those diff drop spacers away and fix the diff c/x angle issue the right way. Diff drop spacers do not correct the c/v axle angle. With up to a 4” lift your c/v axles are perfectly within range of their operating conditions. The only problem is that the driver side needle bearing is not designed to hold the axle fixed at those angles. So we modify the bearing by removing the old one and putting in a solid sleeved bushing. It has no moving parts, it contacts more of the c/b axle surface and it eliminates the need for a diff drop spacer all together. Diff drop spacers have a overwhelming amount of negative side effects when looking at the life of the vehicle. They are NOT a long term fix. The ECGS bushing is the correct way to go.
