That's anti-lockedurm just noticed something might be wrong on the diff.
I believe those safety wires appear to be going the wrong direction?
assuming those are normal threaded righty-tighty bolts, the wires should be arranged to pull the bolt heads clockwise to keep em tight and resist anti-clockwise like in this pic

on the diff there it looks the opposite, it's pulling the bolts looser anti-clockwise and resisting clockwise
