Hi Scotia Stev
My car is a 1999 4/4 with a Ford Zetec 1.8 engine. Some time ago I was trying to find what modern oil to use to replace the diff oil since the oils specified in the hand book are no longer available. I contacted a couple of dealers and the MMC for advice. One of these people, either a dealer or MMC themselves, I can't remember exactly who, told me that a number of 4/4's were fitted with LSD's by mistake because the axle manufacturer had incorrectly labelled them. As it turned out my car was not affected and has a standard ie none LSD axle
