What Jeep did you have with auto locking hubs?

Yes but at first they tried the center axle disconnect which used a vaccum operated collar and a two piece passenger side axle shaft. That system was problematic so in the 90s they just went to a live front axle that turns all the time which is no different than driving around with your hubs locked all the time. They never used auto locking hubs.

The F150 has vaccum hubs but they work the opposite of how the Superduty hubs do. They lock when vacuum is taken away and unlock when vacuum is applied, so if the vacuum system fails you still have 4x4.

And SD trucks aren't like this because..... ? Is there a reason why or is this just a reason for Ford to keep the manual locking hub option?

The manual hubs are stronger and you can have 2wd low range if you leave the hubs unlocked.
