When I was purchasing my Patriot, the sales guy told me that whatever I did, I needed to be at a standstill when I engaged the 4wd. I thought that sounded inaccurate, but I didn't argue, mostly because I could tell he didn't really know what he was talking about. (As mentioned here, the manual says you can engage at any speed, and my real-world experiments have proven this true).

Last night I went to a new owners' appreciation thing at the dealer (kind of cool, actually), and they divided us up by vehicle and had a mechanic point out all the stuff about our vehicle. I was the only Patriot owner there, so we were just making smalltalk. I mentioned what the sales guy had said, and he said that didn't sound right. He also mentioned to me to remember that it was a 2-wheel-drive vehicle until the lever was pulled, which put it into 4wd. Which is wrong. (I have FDI, so I don't know if it's true for FDII or not).

Moral of the story: learn about your own vehicle, because the dealer sure doesn't know about it. That's why jeepforum has been great for me as a TJ owner...anything I want to know, I can find out here. I hope we can build that kind of community for the MKs.

Hmm that was my understanding of how the FDI is in my Compass - it's a FWD vehicle until you flip the 4x4 on - also are there any speed limitations to the 4x4 system? I mean I know I won't be doing 80 with it on - but is there any harm in running it at like 40-50 mph (like snowy/icy surface streets etc)

even with the 4WD lock off it will still transfer power to the rear wheels as needed. 4WD Lock is controlled by the computer so even with it on it will go on and off by itself depending on speed (the 4WD light will stay on however). but with 4WD lock off it prefers to power the fronts only most of the time.

you could leave 4WD lock on all the time and at any speed, the computer will sort it all out. all 4WD lock does is tell the computer you want all 4 wheels powered as much as possible. at low speeds this will give the rear power all the time but above a certain speed it will do what it thinks best.

Does anybody know what axle is installed on a FD1 Compass?

It seems there are diff lockers available for "Dana" axles and these are installed on most jeeps

Sorry, but no. One of the guys at Rock Crawler has investigated that and no one is manufacturing anything at this point.
