I need some info on the 4x4 front axle on the Superduty (1994 thru 1997 F450) truck. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
<o></o>
What axle version of a Dana Axle did they put under the front of the F450 truck?
<o></o>
Is it the same as the F350?
<o></o>
Will theF350 axle interchange with the 450?
<o></o>
Can the front F350 4x4 axle be swapped into a 2x4 F450? And, the steering linkage, springs, etc, as well?

 

first off, there is no such animal as a F-450 until the 1999 model year.
second off, there is no such animal as a 4X4 superduty. if you want to convert a superduty to 4X4, you will need to put a dana solid front axle under it.
then you will need to add a transfer case. to do this you will need to either fabricate a divorced case mount, or change the transmission to a 4X4 style with a married transfer case. if you swap the trans to a married t-case, you will then need to adapt a parking brake system to the truck, because the superduty has the parking brake mounted to the tail shaft of the trans.
