Job 2 differential?
Was told that there were some changes made to the F150 differential sometime in 2011. They referred to it as job 1 and job 2 differentials. Does anyone know if there was a change, and if so, what was changed.

I think they increased the spline count, but don't quote me on that.

Job 2 was when they started building the Ecoboosts. Jan I think. They increased the axle size so all trucks got the same axle but apparently it was due to the EcoBoost's low end torque.
