Is the center locking differential present on 2003 Discovery II models? I thought it was available in the 2004 models only.
Here's what Wikipedia has to say about the center locking differential in the Discovery II (1999-2004)
"The locking centre differential was still fitted until early 2001, although the linkage to operate it was not attached, as Land Rover believed that the traction control and newly-developed Hill Descent Control would render it redundant. The actual locking mechanism was removed in early 2001, before being fully reinstated (with linkage) when the face-lifted model arrived in 2003."

Perhaps the re-introduction of the center locking differential in USA was delayed until 2004.
