I am hoping between the time the article was authored and now that other techniques have been pioneered. Edit* link states both dual and single row units can be replaced without dis assembly. Since I'm not sure what failed in my car it may need to come apart anyhow. When I restarted it it was running smooth just with a chain like rattle so I shut it down immediately, not sure what's wrong with it.

Ghostrider,
You are correct that the 2.5s have a double row bearing, however this is a "serviceable" bearing in that it can be removed w/o splitting the case. Porsche returned to a double row bearing in 2006, but this later style cannot be replaced w/o opening the case so yours should replaceable assuming this is related to the noises you heard.
