Nope, won't hurt anything. It will simply cost you even more mileage.

With the hubs in the locked position but the transfer case not in 4x4, you're turning everything in the front differential and the transfer case, but the engine is not coupled to the front drive shaft.

I generally run mine that way all winter unless I am going on a road trip of any real length.

In the older trucks, the hubs were not very strong. Stick the truck in the mud and pull in 4x4 and BANG! There goes the hubs.

In the newer trucks, the hubs are MUCH stronger. In the '99-04 trucks, the Auto-Locking hubs have a diaphragm inside that pulls the clutching sleeve in and locks the hub. These work great and are very strong, but do require periodic cleaning and service. For the guys that stick the truck in the mud and THEN put in 4x4, mud and dirt get drawn into the hub. This usually locks the hub and will not allow it to release. To fix it, the hub has to be disassembled and cleaned.

I guess the point is that these late model hubs are much stronger than they used to be. There really is no difference between locking the hub manually or automatically. The same process locks the hub.

If you've got Auto-Locking hubs, there really isn't any reason to keep the hubs locked. If you've got manual locking hubs, it might save you from having to get out and turn the dial on the front wheels.

I am not a proponent of driving around with the hubs locked for long when the roads are dry. While it won't do anyhting to your transfer case, when making tight turns on dry pavement my front wheels skip like it is in 4x4. It seems as if the front diff is not an open diff, but locked. Maybe I'm wrong, but the wheels skipping over the pavement is not my imagination. So I think you can do damage to the front diff.

That's what I was hoping to hear.
