The last CV you'll ever need....maybe

I think that is what Billy was refering to. You need to basically drop your diff to slid shafts out, you do have to remove the diff brackets, which includes the 4 bolts you are referencing and the 2 bolts that hold the diff bracket to the frame per side. Then they slide out, but not before your diff is sitting on the floor This is the part that most people do not want to do, so by "dissassemble the diff" I think he meant drop it out of the VX, which yes you have to do.

I NEVER have had to drop my diff to the ground, to get the stubb axles out, EVER...in fact, I say, it would be a struggle to get the diff out before removing the axle shafts.

It can be done with the diff still hanging in the VX....a pry-bar and patience is needed though.
