So over the course of the 5k miles I now have on my X, the shift knob has started to come loose. I just noticed today that the pattern looked crooked, and sure enough I can spin it a bit.

I looked through the How-To/Install section, but no one has anything posted about shift boot or shifter replacement so I could see how the panels come out. Anybody know how to get to the bottom of the knob so I can tighten it up? I don't want to go destroying my interior.

Note: It has the stock leather knob, no interior sport package.
