If you have to pull the rack the diff has to come out. Which means the stupid driveshaft clip has to come out. Then you have to take the front shaft loop.
We've gotten around removing the floor to get the shaft loop out. But the clip in the diff is a pain. We either, rip it out with a pair of vice grips on a slide hammer or if the rack is bad we just grind the lower edge of the rack adjusting nut off to clear the diff.
Grinding the rack let's you keep the driveshaft clip in the diff and just slide it foward enough.
