    I've never heard of a set of hubs designed like that. They would be almost useless for 4wheeling. Unless you tackle a lot of hills you cant climb.
    I believe your misunderstanding terms and how your particular front drivetrain works.

    Locking hubs normally refers to hubs that must be manually locked by turning the inner portion of the hub thus locking that particular hub, this doesnt mean you'll always have power to that hub while its locked though, that would ony happen if you had a front locker, or in the case of an open diff (which is what your truck was sent from the factory with) if that particular wheel was having traction problems.

    What your refering to is auto locking hubs, they lock as soon as you shift the truck into 4wd via electric or vacuum servos (depending on yr model truck) and provide power to one wheel at a time normally, they do not hold or stop the truck on a hill if it starts backing down.

    Do you mean the Auto Trac transfer case? With the Auto4wd button?

    GM has not used selectable hubs on pickups since 87. You can't even retrofit manual hubs onto the current front drive axle/wheel bearing setup.

    ahhh prob that's right...im still new to Z71 so I'm learning all the time...so we don't have autolocking hub's on Z71...i thought most all 4wd trucks have locking hubs to prevent you from rolling back down any steep terrain while in 4wd...i just know from my limited experience that when i can't make it up large hills and start to roll back the truck immediately stops even b4 i have the brakes applied

    also in my window sticker it says rear locking hubs?????

    i guess im just confused

    I won't say that doesn't exist, but I have never heard of such a thing. Ever.

    More likely locking rear differential.

    Don't be offended, but yes, you are. Start by reading your owners manual. Then get a Chilton or Haynes repair manual for your truck. You will have a much better understanding of how your truck works.

    Locking Hubs or (Lock Outs) are on the front axle, you engage and disengage them to engage or disengage your halfshafts to spin your front drive shaft. Locking hubs, when switched appropriately, will allow the front wheels to turn independently of the drivetrain.

    Accordingly, the locking hubs engage or disengage 4x4, not stop your vehicle from rolling down a hill backwards.

    Ford trucks use them the most. A z71 has skid plates, stiffer suspension, Bilstein shocks from what I know. You can tell when a 4x4 truck doesn't have the Z71 package, not only from the missing sticker but from the ride height.
