just curious, i know arb do air lockers for front and rear of gu patrols, but they dont do a centre lock. i havenet been able to find anyone who does centre locks.
does anyone make one? i know that the TI spec has one standard, i assume if you wanted to you could fit one of them to a dx/st model.

The GU patrols don't have a center diff.
The Patrols use a Part Time 4WD system, whenever you engage 4WD Hi or 4WD Lo the drive is applied to both front and rear diffs via the transfer case, the front and rear diffs in effect are mechanically tied together.
The systems using a centre diff are known as full time 4WD and these apply drive to the front and rear diffs via the transfer case and a centre diff or a viscous coupling. This means that the front and rear diffs are not tied together mechanically. The centre diff lock, forces the center diff or viscous copling to be mechanically locked, efectively tying the front and rear drives together.
Hope this helps and doesn't sound too confusing.
Regards, Mark

AH HA!
i get it. it doesnt need a centre diff lock, because when in 4wd mode, the two axles are essentially locked anyway.
the downside, presumably, is that even if you wanted to, you can use 4wd on a grippy surface, like bitumen or hard packed dirt, without damaging something or not being able to steer particularly
well

Exactly right, you can get what they call windup and may have difficulty disengaging 4WD or worst case you could break something expensive.
