A topic of much debate, I know....

The early 01's had it too, but its just easier to look at 99-00 than searching for 01's within the correct VIN/T-case #.
Aublec, you can buy a 2004 CDL kit from lucky 8, or search for a used one on ebay. The lucky 8 kit is pretty expensive, but its a much easier install than a used DI. (no bending...)

The center differential allows 4WD to be used on normal roads (constant 4WD) and can be locked for off-road use (part-time 4WD).
In the dirt a constant four wheel drive can be bogged with only one wheel spinning. This is why most have a central differential lock that stops the action of the center diff and makes it like a part-time four wheel drive in 4WD mode. The center diff lock should never be used on paved roads or non-slip surfaces for the reasons mentioned above.
99-2003 Disco II were manufactured with an "unlocked" center differential (why Land Rover this I dunno, its a good debate). 99-2000 (and part of the 2001s) however, can be modified to run in locked mode if you have the linkage to the xfer case, like Alex said. 2002-2003 you cannot, period (unless you want to replace most of the drive train). 2004 Land Rover put it back in, as they should have - The Jeep Grand Cherokee had a lot to do with that I am assuming.....hehe

Not true... it's permanent 4 wd all the time. The CDL locks the front and rear diffs together so that each diff gets 50% of the drive. So if the front wheels loose traction you still have drive through the rear wheels.

CDL can be added to any D2, you need to either get a transfer case with CDL or swap in the missing CDL parts, these can be purchased at Toddco for about $400 http://www.toddcosuspensions.com/diiilodi.html
Add the CDL shifter linkage and you are all set.

bundu i know its an option, but thats some damn time invested/work if your doing it on your back with jack stands/blocks and hand tools like most of us here would have to....take the exhaust off...drive shaft...all that chit...no thanks...lol
yeah my explanation sucked tweak. i am sorry guys, was trying to make it easier to read. epic failure. hehe

I agree that there is no point in adding the cdl. if people would just take the time to understand the specifics of what they were buying before they blow a bunch of money they would save themselves a bunch of headaches. The problem with all the 4 wheel drive questions is that you can't explain a drivetrain system to people who don't understand how a diff works, or what it means to lock one.
