Is the standard Dana 30 on a ZJ a open differential ?

Im just wondering, on the Quadra trac ZJ's with the Dana 30 in the front, and the Dana 44A on the rear. Are the 30's locked or open differentials ? Or are they limited slip ? I know the 44A's are usually limited slip like mine is on my 5.9, however the dana 30 on my 5.9 doesnt have the LSD tag on it. So im not sure what it is.

Open up front, I don't think any ZJ or XJ came with any sort of front locker from the factory.

Above people are wrong :P Quadra Drive systems on the WJs came with limited slip front and rear (Vari-Lock). Quadra Drive II had a more advanced type of limited slip(if I recall correctly). Quadra-Trac on ZJs none came with a front LSD from factory.
