Locking hubs

[Simpleman87]

I have a question. My hubs say auto and lock. Are my hubs automatic?

[Ironkey]

Yes they actually give you the option for both. They are usually in the "Auto" setting allowing you to shift on the fly. You ALSO have the ability to manually "Lock" them at the hub like the good ol' days

Do you have an esof (Electronic Shift On the Fly) control on the dash? If so then yes they are automatic. However if you get stuck before you switch to 4x4 on the esof control sometimes you have to manually turn the hubs to lock. They are probably auto otherwise they would show a free/lock position on the hubs as far as I know.

Make sure you don't drive around with the hubs locked though cause it will wear out the hubs and cause excessive wear on the other 4x4 parts that aren't meant for continuos use. Also your mpg will go way down if you keep them locked. I only lock mine when the situation gets sticky or I know I'm gonna need it.

once every month or so I usually lock mine in on the weekend on a ride to get beer or something like that, while you dont want to have it continously moving, once in a while it is a good idea to make sure everything is good in the front end

Ah good point. I forgot to mention that. I also do the same thing just to keep it from rusting or binding and it lets me know its all working right. As I just found out 2 days ago I have a bad ESOF relay.

I'm not saying you are wrong, (It may be different on other trucks) if you know you are going to need it then by all means lock the hubs to be sure, but I have never had a problem just using the auto position on the hubs and the turn button on the dash to go into 4 wheel drive. I have seen this issue pop up on the org before, some guys saying the vehicle has to be in motion and the such. My truck (an 05) will engage into 4x4 at a dead stop, no need to have the truck moving, and no need to have the hubs locked. If you have an issue with your vacuum lines then yes your hubs will not lock in auto.

When your at a stand still and you switch to 4wd the actuator motor engages the t-case but the hubs don't actually engage until you begin to roll. This is why they say guys have issues when they wait till they get stuck to switch to 4wd cause their front wheels won't roll if they are stuck thus not engaging the 4wd. So they have to get out and manually lock the hubs. Hope that helps
