I searched but couldn't find an answer. I have a 2004 2500hd 4x4 LLY and I'm trying to find out which rear diff. it has. Any code numbers or identifying details would be appreciated.
Be aware-- many of the auto parts books are incorrect and still list the 10.5 as the right gear- and the parts will not work- Honda is correct-- it is 11.5 gear. I believe that Dodge uses the same rear axle.
