So maybe someone can shed some light for me. How does the Center Diff / Transfer Case on the Disco 2 03 function. Is it like a limited slip? I own/run a BMW shop and the modern transfer cases operate with an electric motor that engages clutches which in turn engage the front driveshaft to send power to the front wheels. BTW I know this one is not a center locking diff. Although depending on how this thread goes i may end up exchanging it for a locking one.

 

The repair manual should answer all your questions. I attached the link for the manual if you need. I believe it operates similar to limited slip, in that you must have both front and rear shaft connected and it directs power to the differential with least resistance. If you remove either drive shaft, your vehicle will not move. http://www.landroverresource.com/doc...hop_Manual.pdf

 

a D2 transfer case is different in the fact that there is no 2wd, the shifter in your center console only changes from high to low bear ratios the truck is true full time four wheel drive

 

Generally, an unlocked transfer case operates like a regular differential, NOT like a limited slip. That is, if the front axle loses traction (or if the driveshaft becomes disconnected) then the rear wheels will not receive enough power to move the vehicle.

The case can be locked on some vehicles up to 2003 (check the section in the manual on setup for a 2-wheel rolling road). It's also possible to retrofit the lock mechanism from a D1 to early D2s if the appropriate transfer case was fitted at the factory.

 

Thanks for clarifying that. I was not sure on the limited slip part.

 

The Disco differential is obviously nothing like the BMW setup. The way it works is that on "locking" versions of the transfer case, a lever moves a dog clutch backwards a bit to engage or synchronize the front output shaft of the transfer box to the rear output shaft, creating a single, turning unit for both outputs. When the dog clutch is disengaged it acts like an open differential with each output shaft working independently.
