The t-case on my 2010 is making some noise. It has just under 150k on it.

In the next couple of days, I'm going to replace the fluid on the outside chance that will cure things.

In the meantime - thinking worst-case scenario - I'm looking at good used and rebuilt units. Some companies claim the t-case is the same from 2004 through 2010, others say the t-case I need has to be from 2007 through 2010 vehicle.

Which is right?
