I just bought a "94" bronco yesterday with warn premium locking hubs, silly as it is, I didn't ask how to engage the system. [i have the paperwork he'd just replaced them.]

The truck has a 302 with an auto eo4d trans and push button 4 wheel drive.
I realize I have to lock them in, then what? last thing i want to do is screw up.
Thanx, Clay.

 

I would think that you would need to engage the manual hubs (both sides) Then just push the 4x4 button. (or if you have a manual case Shift it to either 4Hi or 4Lo.

I know on my truck that is all you do. It involves me getting out of my truck, but I have no problem with that.

Also I have the Warn hubs that require you to turn the **** almost 9/10's of the hub. rather then the 1/3 like stockers or the cheaper warns.
