Sounds to me like the Dealers listing is a simple metric conversion, not a whole new axle from Corporate
235 mm = 9.251968" rounded off = 9.25"
After a quick visual inspection on a dealers lot, the 2011 rear looks identical to my 2010.
Someone should talk to a tech thats had them both open and worked on them,
or maybe there are different part numbers at the parts department.
