yes please - if you can share the pic - also which kind of difflock it is ? LSD or rear? thanks.. maybe your manual says something...
A center diff-lock only locks the output shafts that come out of the gearbox, this only means that the front and rear axles turn at the same speed (50/50 drive split between front & rear), the actual front and rear diffs are still open, its helpful if you get one wheel up in the air, but get cross axles and your just as helpless as everyone else. Thats when you need full diff lock on your front and rear axles.
An LSD (limited slip diff) works in a different way and isn't quite useful as a locker.
