Hi y'all.
Im trying to swap my v6, 15's diferential with a 3.90 LSD. I have the axles and everything ready to go.
I actually attempted the swap last weekend, but. . . I couldn't get the driveshaft to come out of the differential.
I tried taking off the 8 bolts that mount the driveshaft to the diff; I unbolted the safety loop to see if it had more play; I even took off the bolts that mount the shaft to the differential, but I couldn't get it to come off.
I even loosened the differential bolts to back up the diff a bit, but I couldn't make it happen.
What am I missing? Does anyone have any advice?

I know the 2015+ cars have a ZF built rear-end, and thus it's not the same as the 2014 and below rear-ends, but I would think their drive-line connection is similar between the diffs. If they are, the drive-line coupler should unbolt from the rear-end flange, not pull out of it. Here's a pic from the service manual for the older LX rear-ends:

I have had mine out and in multiple times now and I have had to use a hammer and hit the CV joint to get it to start freeing up. I not saying beat on it but hit in a slight direction away from the mount (rear or trans) and it will start to break away from the mount.

I did some reading on changing gear ratios and if he's loosened any of those boats that he's got listed it could have changed the spacing distancing between the gears and it all has to be reset now in better words everything has to be taken apart and remite to specifications?

You will need to get two pry bar
to pry the rubber isolator out of the holes where you took out ur bolts it will be hard you can do by yourself but easy to get friend to hold one pry bar and use the other to pop it out. Good luck
