Since I hadn't actually investigated whether a 5.5mm socket was available, I offered the most common shade tree equivalent socket size to the 5.5mm (i.e., 7/32nd). :) Now I'm going to have to buy the correct-sized socket to have on hand for the next cabin filter change, because an off-size socket risks stripping the bolt edges.

Snap-on is probaly the best domestic tool supplier, but if we're going high end, we can go all the way with actual high-line European tools from either Facom and Hazet. Hazet is a German company and supplies many of the German auto manufacturers with their "factory" service tools. Facom, I believe, is a supplier of Ferrari tools and is a French company. Both also offer 5.5mm sockets, but obtaining them requires more leg work than than the domestic links posted above.

A 7/32nd socket works just fine (equivalent to 5.7mm).

Thanks, that's what I concluded but I wanted to be certain. My CTTS is approaching 70K on the clock and I plan to monitor its condition.

The rear is the one that fails.

I did a search and am guessing it's the rear one based on photos that have been posted, so this may be a dumb newbie question anyway.

The parts diagram shows both a front and rear cardan shafts. Is the one notorious for failure the rear cardan shaft? Have there ever been problems with the front one as well?

New to my CTTS, and have been perusing the various boards looking for ideas regarding things to "upgrade" it. A little more power is always a good thing, so I've sort of narrowed my focus to starting with either a i) secondary cat bypass set-up (probably Fabtech unless someone can suggest a better alternative); or ii) an IPD intake plenum. I'm interested in opinions of those who have done one or the other (or both), and your recommendations as to which is better as a first mod. TIA.
