Hubs locked?

Just curious if drving around with my hubs locked in 2wd will hurt anything.? Wish i had auto hubs sometimes when i need that launch for a ricer. Wouldnt be something i would do all the time. But if i new i was goin out with a bud planning on smokin up the streets for the night if it would be ok. Thanks by the way its a 03 7.3l.

If there locked in 2 wheel drive they ain't locked!!! And MPG isn't affected. If you mean locked in ( meaning locked into the front diff) this is fine and won't do any damage. I use to leave mine locked in all winter.

I keep mine locked at the hub all year. Kick it in at the dash only when I need 4wd (which is often) No real noticible mileage difference.

I had a right front stuck locked for I don't know how long. I started getting a vibration on that wheel, and that entire hub was worn out and had to be replaced. I do not suggest running with the hubs in the locked position at all times. It will cause wear and tear. Your tires are driving your front end, and the transfer case. Kinda backwards from the way it's supposed to work. Sending power from the transfer case to the tires. This is just my reconmendation and my opinion. I've ran 4x4's for awhile now and if there were ok to be locked all the time, then there wouldn't be a hub there for the option. Trust me, I know it's not convient(sp) but, nor will replacing your transfer case when it blows from all those 4x4 launches. Sorry, don't mean to be a Grinch, I've seen too many transfer cases blown due to loading them up in such a manner.

Again, I'm very sorry to sound like a turd head. Just my $0.02

If they are locked you will notice a mpg difference between them being locked and unlocked due to the fact that you have more moving parts now.. So you essentially due put more wear on the parts such as front axles/u joints and front diff and front drive shaft joints. I personally never leave mine locked for long period of time. I go out the night or day before it snows and lock them and then the day after i unlock them.

Im not saying you will have problems. Im just saying that you will notice a difference in the mpg due to the fact of more moving parts thats all. Look at dodge and chevy.. They are locked all the time they dont have hubs.. Its locked all the time so the parts are always moving all the time. Do I personally think its a good thing no. I prefer to keep as little moving parts as I need. Less things I have to worry about.. So I like fords way of having lockable hubs.
