Front air dam removal
 

I've read that there are instructions in the owner's manual for removing the air dam/lower fascia.
Blowed if I can find it.
I've found a pretty good set of instructions on the Chief products website however, but would still like to see a diagram showing exactly where all the removal screws or plugs or what-do-you-call-them are positioned.
I recall the one on the old WH was fairly straightforward, if a bit tricky to line up the corners when putting it back. (broke one side on the ferry to Fraser Island!)

The instructions you found from Chief are as good as you will get, I think they had photos as well on their web site.
There are 7 plugs to remove and are easy to find. The hardest part the first time you do it the pulling the bumper off. Just start and one end and don't be scared to used a bit of effort.
I can now remove mine in under 2 minutes. Putting back on is just as easy.

It snaps back in place quite easy as well (found out after ripping it off accidentally during some sand duning).. so it can take some punishment.

You can get spare plugs from a Jeep dealer - I butchered a couple trying to get them off to fix the bumper once I got home..

If you need a video demonstration you see how it's done in this YouTube video

Ok, I did it today, found it pretty easy to get off, putting it back was harder though. Getting the corner lugs in was a bit tricky, would be easier with two people holding it. Also, I didn't get the central plastic hooks back in place ( as far as I know) because with the new tow hooks protruding you have to get the panel over the hooks, then there isn't enough room to see where the plastic hooks line up. I don't think it's going to fall off though!
