Dress/SLIGHTLY bevel just the opening at the root with a fine file. Work very lightly about 1/8" into the box on all sides. Check for burrs and sharp corners on the joiners, but don't grind them down or you'll end up with what I did - joiners that are tight at the root, but flop around inside the box.
Try the fit with both joiners on both sides...usually there's an optimal fit with just one arrangement, then work from there. What I found was leaving the joiners in the tips helped, as will a few hot days in the sun. After a bit, the boxes will self-relax a bit and disassembly will be easy.
I found that this worked on my second Extreme (after the first one met an untimely demise) and my current Pike Superior had a similar, though not as tight, joiner fit when new and all was well after slight fitting work and time in the sun.

I picked up a Xtreme and the outer square carbon joiner is way to tight to allow the wing tip to slip on - what is the best solution for this? Sanding it lightly? (make me itchy) ;-) or some sort of lubricant? Or what?
