Yeh, looks can be deceiving (lol), a great thing with a auto lokka ,you can still drive in 2wd with the hubs manually locked in, no problem, so I just unlock them when im airing up , saves getting out/stopping twice.
Anyway, all you boys with full Auto hubs, are crazy if you don't manually "lock" your auto hubs in doing glasshouse tracks, especially the tracks you drive Troy (haha)
