The 04 4 wheel drive system is said to be one as advanced as ones found in LandRovers and expensive 4x models. Does anyone know exactly what these things do in 4 Low?

 

No, but we'll find out the first day that I drive one! Seriously, though, I really do think that we should have an option of a solid front axle and some super-low gears, such as a 6.72:1 or something like that, I'd sign up today for it. I would like to test the 4x4 capabilities of the 2004, though.

 

Thanks for the reply, anyone else have any info? Co worker mentioned that it may be the system where you mash the gas to the floor and the computer takes over controlling wheel traction and speed? Sounds more complicated than anything Ford would use. I dont know, thats why Im asking. Thanks

 

Saw an infomercial for Land Rover on tv a while back and they talked about their 4wd system. Said something about when you put the transmission in 1st gear it uses the brake system to keep the vehicle moving at a slow speed (7mph I think) for when you are on a hill descent. Land Rover's web site should have some info about it. The FX4 is supposed to have a special throttle program built in for 4X low that keeps the truck from lunging too much incase you get bounced around the cab and accidently hit the throttle.

 

just me, but i believe the correct spelling is transfer......just my .02 cents

 

nice

 

The front hubs are vacuum operated on the '04s.
There's a vacuum diaphram on each hub that disengages the hub when the vacuum is applied.
Yes, Virginia. That means, when you loose vacuum the hubs will be engaged.

The '03s only disconnected one side of the front axle.

 

does anyone know if there willl be an option for an "auto4wd" fulltime 4wd system (selectable) as on the current sierra/silverado? such an option I think could well be worth it for foul weather driving. Not that I really use 4x4 much at all on my truck even in bad weather. Just a lighter throttle foot

 

I don't think there will be an auto4wd system. Still just the 2h,4h,4lo sys.

 

Your right, its transfer.

 

Thanks for the info CSPinson. That was one of the coolest features I thought on the then new '99 chevys when they came out. But I so rarely use 4x4 on road in my '98 as it is that now I'm not sure if it's that valuable an option. I guess Ford didn't think so then either. With the dial switch it's not hard to turn it on as you need it anyway.

 

No problem. That would be a neat feature, I wonder if GM has a patent on it though. That might be why Ford doesn't make a sys like it. I'm sure if you really need the traction in bad weather the 4X hi would work just as well.
