I naturally assumed it to be the H260 wagon LSD varient with 4.7L capacity, but when I changed the diff oil I was surprised to see it not taking more than 4L (3.7 seems approximately right).

Now I'm wondering if it's a H260 with factory diff lock. There's nothing in the cab to indicate having a diff lock.

This is my first patrol since December last year, still learning about it.

Here's a list of diffs from the 2007 manual
