my 99 ranger has a vaccum system, It is such a good system. Until it leaks, partially engages 4x4, and chews off the splines when the hubs disengage under load due to the leak. I was so pleased, I took off the vaccum hubs and replaced them with aftermarket manuals. Can you sense the sarcasim.

I work at a ford dealer for a co-op, i've already had 3 different trucks with the same problem. The solonoids fail, the hubs seize up if you don't use them like once a month. Its a good design, but its not good if you don't use it.

why don't you check out my Video of me offroading my 2004+ F-150. I've replaced 2 IWE hubs, one happened that day, it's an okay design and is very simple to understand, but oftentimes you will have an IWE solenoid failure, blown fuse, vacuum leak etc. and the IWE's will lock, this causes your hub to fail on the street and you may not realize until you take it offroad.

wow, thats a vacum gun and its a vaccum diaphram. its very simple and very cheap technology. old and proven but used in a new way. if it breaks its just a matter of replacing some rubber. i dont know how ford does it. the things they come up with make me scratch my head sometimes. its just wierd.

He said it perfectly, "It's a more expensive way to build it" So when it breaks they can get more money from you. I have been looking at these cardatavideos and wonder why they only compare to Chevy in a select few categories???? Probably because they know chevy is better. P.S. I love how only two people in the audience drive 4X4's such a great group of critics

Why does that knuckle look larger than whats on the truck. Its a cool system unil you get a vacum leak and it engages while your driving.
