Looking to see if anyone has some insight (or a parts list) on how they installed a F250 axle and the parts they used or modified. Have a 2011 E350 with the 8x6.5 pattern and a 2010 F250 axle with the 8x170 lug pattern. Probably have to restud the hubs but now I’m wondering what I need to do for the rotors, calipers, etc to get this to work right. Hoping to not have to buy sets for both and hodgepodge it all together.

2011 E350 is 8x6.5 (which match the wheels I’ve already purchased) and the new axle from the 2010 F250 is 8x170. Some people use an adapter on the rear of the van to swap it to 8x170 but I didn’t do enough homework so I’m gonna swap the front to 8x6.5 (do it the hard way). ��*♂️
Yup.....you can get spacers/adapters to go in either direction.......but already having wheels can be a problem.....you can sell the 8x 6.5" wheels here and re-buy them in 8 x 170......you wouldn't be the first member here to do that.
....then use a 1.5"-2" spacer adapter on the rear to get 8 x170....or carry two spares
If you are planning on bushwhacker fender flares then you'll need spacers on the rear anyway.
That lets you keep your wheels, BUT you're pretty much stuck buying another unit bearing from them when you need a replacement. They're expensive, and you're not exactly going to get one in a hurry if you need it.
I personally have the stock E350 axle with an adapter. I like that it makes the front and rear track about the same width. I also like that I was able to buy a pair of Timken unit bearings for $350 instead of the $1k for the redrilled ones.
As pointed out, putting the 1.5" (1.75" is close to perfect) lug adapters (8x6.5 to 8 x170mm) on a full floater rear axle is a very easy solution that also widens the rear track to match the front axle you are looking to install. This keeps all your wear parts easily sourced.

This ^^, I'd adapt the rear instead of the front. Lots of good reasons it's always been done this way.
