Hello. i'm in Salem, Oregon. i'm considering buying a 1997 F350 crew cab 4x4. there's a metal tag pinned to the rear differential. get that code and do some online searching for ford rear end gears. i know i saw a thread in here somewhere listing codes, too. the truck i'm buying has 4.11 gears, and i would like to have 3.55. or perhaps 3.73. keep me in mind. if you find out that you have 3.55 or 3.73, then 4.11 would give you an improvement. seems lots of guys around here think that even with 3.55 that the 7.3L has enough low end to make it work, and maybe a power chip would help you more. anyways, i'm just barely learning all this stuff, and i don't even know if our axles could swap, but i'll follow this thread and see what folks have to say. scott
p.s. piplayerjdh posted this in another thread "Look at the sticker in the driver side door jamb. Under axle it will have a 2 dig. code."
you can search the forum for words like 3.55 or 4.11 and find gobs of info.
