Fun fact for the Patrol guys! 👌
Some GQ and GU Patrols came factory with a locking rear H233B diff.
Unlike most aftermarket lockers, the factory Nissan locker is actually vacuum operated.
They’re a pretty solid setup, but one common failure we see is the locker engagement ring breaking or wearing out, leaving the locker unable to engage properly.
Another thing a lot of people don’t realise — the factory locker diff uses different-length axles compared with the standard H233B setup, so you can’t always just mix and match parts.
