4WD Operation
Need a little info that I can't seem to find on any site and it's pretty easy to answer.
On the 2005 F-150 4x4 does it have a full-time 4WD option? I know it has 4H and 4L, but in 4H can you run at normal speeds (highway) and leave it on without messing it up. I had a 2000 Jeep GC that had 4 Full Time, 4 Part Time, and 4L. The 4 Full Time allowed for running at highway speed with no problem and was great in slick Idaho winters. My wife goes tomorrow to pick up my new F-150 XLT Crew 4x4 (I'd do it but I'm over seas right now), and I was just curios, I'm getting it regardless but just wanted to know.
If anyone knows of any website that explains the 4WD operation on the 04-05 F-150 please let me know. Every site I find just talks about it's pay loads and towing capacities.
Thanks y'all.

With 4H you can run higher speeds than 4L but to my knowledge it is a conventional 4wd system. Even though the gearing will allow you to run 40 or 50 mph is is designed for slick or slippery surfaces. A full time 4wd system uses a traction control system that transfer drive force to each wheel as needed. This allows you to drive and turn on pavement without harm to the tires and drivetrain. No where in my manual does it state anything about a fulltime system on these trucks.
Hope this helps.

As the front hubs are automatic, it is very easy to switch in and out of 4wd. Just make sure you are under 55mph when you go into and out of 4hi. 4lo you have to be stopped. When needed, I am in and out of 4hi a good bit.

The difference between a full time 4WD and a part time is in the transfer case. Full time systems allow for the front and back to spin at different speeds, similiar to a open differential. A part time system is locked front to rear. This is why in our trucks it is not recommended to drive with the 4WD engaged on dry payment, the tires cant slip a little to relieve the stress.
NoH20,
If there is snow/ice or wet roads you can safely run the 4WD in 4HI up to 55 mph. I would pay close attention to tight turning if the roads are only wet.
