If he said you have to turn them on the out side then you probably have Manual Hubs, in that case it would be true,
But you should post a picture of the wheel hub, or tell us a year of the truck, some have straight up lock and unlock, and some have it where its unlocked-auto.

Either it has ESOF or it doesn't. If it has the instrument panel selector, then it IS equipped with ESOF, which operates in a manner where 4x4 can be selected at the flick of a switch provided the pulse vacuum hubs are functioning properly. If this operation also requires manually engaging the hubs, then either the PVH isn't working, or the hub locks have been changed to a manual lock set up.

There two types of hubs.

Manual locking hubs. These hubs are either free or locked. Then you have auto/lock hubs. These hubs will lock in automatically when the transfercase is engaged. How ever they can also be manually locked in.

Most likely you have auo/lock hubs. Meaning all you should have to do is flip the switch on the dash to 4wd. How ever if need be you can turn the hub to lock. Which will lock the hub in so your front axle powers the wheel.

Now the hubs can be replaced with Warn or Mile Marker. These hubs are aftermarket and are either free or lock. These are considered manual locking hub.
