a front auto locker is about the worst thing you can will on anyone who might have to engage 4wd in traffic. If you thought the side-slip was impressive with a rear locker, wait til you get up to 40 and the front one decides to load or unload. It turns a commute into an adventure.
Shoot mine does that sometimes on dry pavement in 2wd. Back end steps out while doing 45mph down the road. Doesn't happen much. But it has happend.
