Unless you are talking about a steering knuckle drop there is no diffrent to a bracket drop on a IFS or a suspension lift on a solid axle. The differential will still be at the same height from the ground. So that's a mute point. This conversation was about a cv axle bind on a IFS due to a larger shock being installed...... to correct bind you either go back to the shock designed for the geometry of stock IFS. Or you drop the chassis to IFS height to correct geometry and not have the suspension sitting at close to full extension. Long story short if you raise height of vehicle with a shock or spacer, you must raise the chassis the same height to maintain proper suspension travel, suspension geometry, cv geometry and the correct steering .
