SR5 diff

Hi guys I noticed a device on my front diff (IFS) in between the diff and passenger side Axle tube.
It has two vacuum lines and two electrical leads in it.
I gather that it has something to do with the auto hubs but I can't see how.
Can anyone enlighten me as to how it works, because I don't like not knowing how something on the truck works.
Cheers Struth

Its the ADD on your front diff Struth. It is a vacuum operated arm that engages the left axle to the diff and when you push the button on the short shifter you not only get 4wd but you engage the front axle as well

Thanks guys, it seems common consensus is that this is just another thing to stuff up and better off turfed.
I would imagine it could be as simple as fitting the axle tube and axle from a truck without ADD, then bolting on manual hubs.
Is it that simple

Not only can they stuff up.... they just do not always lock even when "operating correctly".
Not sure about changing them..... My SR5 has standard manual hubs. I would have thought you would just disconect the auto system, block off the vacuum and fit manual hubs courtesy of your local wrecker. But I would wait for futher advice.
