It appears the OP's question has been answered so I hope my mini hi-jack is overlooked. I have an 07 Sahara auto with 4.10' 2x4. I'm about to begin converting to 4x4. I've priced rubi fronts because I was told that was all that came stock with 4.10 up front. Forgive me if this is a stupid question but, what you are saying is, Jeep offered a D30 front in 2007 with factory 4.10 gears? Any other years/models with D30/4.10's? Again, forgive the hijack, it appears the question has been answered imo.
