Anyone know what the fording depth of a 2004 F-150 FX4 might be? The owner's manual says something like "don't submerge the axles," but I want to know for the next hurricane that comes. I drove my old 2WD Isuzu pickup through water so deep there was a bow-wave higher than the front of the hood with no apparent problems, so I would hope the Ford is somewhat deeper than axle depth, even if I have to change the differential lube afterwards. I can't figure out where the engine air comes from either - I don't want to vacuum up water and lock up the engine, but it seems to just mysteriously come from the inner fender. Thoughts or experience, anyone? I'd prefer a reference to published info, but stuff learned the hard way is welcome, too!

 

i have been in water 35 inches deep, but i am running 38" tires the diffs have a breather tube on them that runs from your diff up to your bed on the back and the front one is alittle shorter, if you want better fording, extend those tubes, my stock intack would suck up alittle water when i would just plow throu the water it would splash all the way over the top of the cab, to combat this i got a k@n fipk2 and built a custome heat sheild/watermud pretector, or you can do this trick get a long peice of flexable pvc hose the size of were your filter matches your intake, and when you need to ford atach it to where your filter goes and atach your filter to the other end, and then you can get air from wereever you want to run that pvc hose, get my drift?
