1. Once I get all of the bolts out, does the axle just drop out or is some wrangling necessary? If so, any tips/pitfalls?
Once the bolts are out grab the CV joint and give it a little tug. Mine came off very easily.
2.Upon reinstallation, does anything need to be lined up besides the holes/bolts? Specifically, does the shaft need to be installed in any particular way? Are both ends. ie inner and outer, the same?
No real issues re-installing them. There are two groves on the axle, near the inside joint if I remember correctly. And there is a slight lip on the outer end of the axle. You will see what I am talking about. Not sure if it matters, but that's how they came off, so that's how I put them back on.
There is a small lip on the wheel hub and the differential side as well. The CV joint sits inside this lip. You will have to line up the bolt holes, but that is very easy. Once you get the bolts in everything should fall into place rather easily.
Replacement bolts? Call Frank at AW auto parts (Board Sponsor). If he doesn't have them, try a Porsche dealer. Can't imagin they are too expensive. But I have said that a few times and have learned to keep my mouth shut.
Good luck
