Front axel engagement

[lowrollin70gmc]

Many newer trucks front hubs have "Auto" and "locked" as positions as a way to manually over ride a broken front selector.

I don't like auto hubs because more stuff breaks and I like positive engagement. If the weather outside is nasty snow and slick I'll engage the hubs before I start driving. Then just shift the t-case if necessary. Easier to engage them before being stuck and won't hurt if you're driving on slick surfaces. I've had electric and vacuum hubs fail leaving me with a 2WD truck somewhere I shouldn't have been.
