Superduty Gears in an Ex???
Can someone tell me if the gears from a 2003 Ford diesel F350 crewcab dually 4x4 will fit in a 2005 Excursion 4x4??? I looked at a 03/04 at my work and the front axle appears the same, confident there. The rear axle housing on the SD looks to be beefier and a bit different. Are the ring and pinion gears compatible??? There is a set of 4.10's for sale on craigslist for cheap I just don't know if the rear gears are the same with a different housing or just not compatible. Thanks

Sorry, but no, you can't fit a 2003 Ford diesel F350 crewcab dually 4x4 gears into any Ford Excursion. The Excursion has a Dana 50 front axle and a Ford 10.5 rear axle.
The 2003 superduties used dana 60 front axles. The ring and pinion are not interchangeable with a dana 50 that is on the front of the Excursions. However,
The Dana 60 can be pretty much just bolted up to the Excursion. A full axle swap. The rear axle of a Dually is a different story. The 2003 superduty Dually has a Dana 80. Totally different set of gears.

pretty much what he said. gears can be had for decent prices. i prefer motive's performance line, they are as quiet as OE for around half the price. I want to say my front gears cost about $225 and the rears were $300. The install was the expensive part, i paid my local shop (drive line shop) around $900 and it took a day and a half to do them.

What they said, plus...
It's really not advisable to install used gears. The ring and pinion take a set together, when installed in a different housing they will take a different set. The result is wear on the tooth faces.
You could 'probably' get away with it on an Ex front, where the gears are idle 95% of the time.
But even that would only make economic sense if self-installed. It would be crazy to pay someone to set them up.

Good catch Howler, I should have said this on my first post.

Thanks Digger. I didn't see it as left out, but as extra info.
Even more extra...
A part-time front axle like our Dana 50 is a good place to learn diff set up. If the set-up reasonably good it will last because the gears are usually idle, only working in 4WD. So a set-up that would die in 50K miles will last years. Unless you are in Alaska or similar 4WD all-the-time conditions.
This does not apply to AWD, front axles w/o locking hubs, those weird axle shaft discos, t-cases that always spin the front shaft, etc.
