If I have a front lunchbox locker, will it only work (aka pop) when I'm in 4x4 or all the time?

With the DTT there should not be any noise at all, shouldn't hear anything
of course the ARb would be quiet

For how much it's going to cost to install a lunchbox locker in the front might as well install something good like a DTT or ARB for a little more $$$ as the install labor will be the same.

The front D30A cross pin is held in place with a roll pin(as seen in the pic below),not a bolt like a normal D30,so the whole carrier has to be removed to install a lunchbox locker,which also means the whole diff has to be removed and the backlash reset.



The above is a D30A carrier for a '05 KJ's D30A that I bought new from the dealership and installed a DTT.

All I can say is spend your money once and do it Right the first time.
Skip the "Extra's like fast food, coffee from a coffee shop and all that,
that cost extra's!
Spend the most on the "Locker" that you want/need, then have it installed
professionally if you cannot install it your self.
It will last a life time with proper maintenance and satisfaction!
