Can any body tell me if the 2010 XLT 4.6 has the same carrier in both front and rear diff,s

 

no they are different

 

All of the non-Raptor fronts are open diff HP 8.8s. The rear could be an 8.8 or 9.75 and either could be open or limited slip. If the rear is an open 8.8, then the carrier might be the same. A check of the bearing part numbers could help confirm. But the rears are 31 spline and fronts are 28 spline so at a minimum the side spider gears are different.
