Default Which differential is this?

See this thread, Post #93. That tag does not look like the PN tag, but some sort of date tag. Looks like 9/12/07. If that's the case, and I'd bet it is, it's an '08 diff.

For reference, the Japanese typically format their dates by Year/Month/Day. If that is the case, then the date on the tag in the first picture is December 7, 2009.

It might be YY.MM.DD so that diff could be from late 2009 making it a MY 2010.

That does look like a date, but got it 'murricanized.

Date on the "58J" from post #1 is Dec. 7, 2009. Consistent with a model year 2010. On the "48J" carrier in post #3, 5/15/2008.

The 2011 carrier I installed in my 2008 has the "58J" tag on it. But I can't read the date.

Alex, have 'em shine a light through the axle hole. On the 2008 - 2009 "open" carrier you can see all the way through it. With the 2010 & later torsen equipped carrier, no light gets through.
