Unlocking manual hubs question

Hey all,

Getting ready to install Warn hubs today and found this:

"From what I understand you are not supposed to run with the hubs engaged unless it is in 4x4."

Other than poorer fuel economy, what is the downside?

I can't see my wife going out and locking/unlocking everytime she wants to use 4-wheel drive.

I foresee a lesson in locking hubs in my future.

Thanks,

I see no downside in running the hubs locked other than the reduction of fuel mileage AND the added "wear-and-tear" on the front axle assembly. After all, many 4WD vehicles were built without manual locking hubs for many years. When conditions get bad here I just lock the hubs of whatever vehicle my wife is driving before she leaves home...then she just shifts into 4H when needed. My wife fully knows about how to lock up the front end on all our vehicles (and to unlock when she reaches 2H conditions), but when I know she will need 4x4, why wait until she needs it before locking the hubs?

Unnecessary wear of the axle u-joints and needle bearing in the Unit Bearing Hub.

When I lock the hubs I hang a small red strap on the rear view mirror so I don't forget to unlock them. I have CRAFT syndrome.
