this may take a while,, in the meantime this was at the Gilmore Museum about 8 years ago.
comparing 2 axles, one from a 2010 big bearing 28 spline from a 2wd reg cab 2.3 auto,,the other 2004 4x4 small bearing, 28 spline.
both are open diffs. the 2010 diff does not have a tone ring at the ring gear.
For 2010, if you find a big bearing, it isn't necessarily a 31 spline. I don't know what a 2010 4wd has.

ok, I'm on a roll now, a slow roll though. above is 2004 short shaft at 27-3/16"
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-17%2011.24.13.jpg)
above setting the shafts even to measure total width
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-17%2011.24.40.jpg)
above spacers in center to replicate diff pins for total width
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-17%2011.25.34.jpg)
above 2004 measures 58", 2010 (with tone ring) measures 57-1/2"
the 2010 is 1/2" narrower than the 2004, that is corrected by the disks.

2010 shaft with tone ring, 2004 plain
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-17%2011.30.01.jpg)
above the center thickness of the disks is freakin' huge at 3/8". they are approx 1/4" thicker than drums.
so,, put the thick disks on the narrow 2010 ,that equals the 2004 with drums so the wheels are in the same spot.
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-17%2011.37.17.jpg)
above rear 2010 disks are 11-9/16" dia, 3/4" thick and vented. that's a lot of brake power for a reg cab 2wd.
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-16%2015.47.28.jpg)
above 2 diffs. 2004 has ABS sensor on diff, 2010 has a tone ring at each wheel. the unused hole
in the 2010 does not line up where a tone ring would be.

above 2010 outside of flanges side to side, subtract 1/8" for opposite bar, get about 52-7/16"
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-16%2015.47.00.jpg)
above 2010 on top, note the end flange is rotated 90 degrees, narrow top & bottom, long front & back.
they are also not the same distances as the 2004 flanges.
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-16%2017.06.58.jpg)
above, the other ends were even. this shows the 2010 is shorter by about 3/16"
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-16%2016.55.53.jpg)
above how I measured the shafts
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-16%2016.10.55.jpg)
above 2010 again, about 52-1/2 flange -flange
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-16%2016.02.15.jpg)
above 2004 subtract 1/8" get about 53-1/16". this is about 1/2" to 9/16" wider than the 2010.
the tube extensions where the seals go are equal on both axles, so the 2010 is narrower over-all by about 1/2" or so.
![](http://i463.photobucket.com/albums/qq356/pjtoledo/2016-03-16%2017.01.54.jpg)
above long shaft 2004 at 30-1/16" its about 1/4" longer than the 2010 at 29-13/16"

above 2004 again

above ends again

above the most important pic. the blue squares are where the bearings ride, measurements are
from the end of the axle to the bearing.
if I put in a 31 spline carrier and the longer 31 spline 95-01 Explorer shafts the bearing surface may be out past the
bearings in the housing. I may have to get the EX shafts shortened to fit this housing.
the offset for the brakes I can handle.

above 2010 flanges again
and lastly, anybody from Michigan should know exactly where this picture was taken.
