Rangers never had a 4.56 factory option. Your axle is a 4.10.
In 2008~2009, Ford added the R8 Ranger code for the 4.10/31-spline/3600lb axle w/Torsen geared LS that was an option in those 2 years on the FX4 Off-Road. The 4.10/28-spline/2750lb 8.8" axle w/Traction-Lok clutched LS used code R7.
For 2002~2007, The R7 code applied to any 4.10 limited slip 8.8 regardless of whether it was a 31-spline/Torsen or 28-spline/Traction-Lok.
