2006MY build. RHD
I've been around Jeeps for a bit and there is a significant difference between the Dana 44 and the Dana 30. The first and most obvious difference is the fill plug. Dana 30 uses a pvc or plastic filler cap and the 44 uses a steel/iron plug. That and the obvious shape and bolt pattern is the other.
That being said, any reason why my build sheet would have a Dana 30 for the front when it is obviously a 44?
P.S. And before the trolls start with their answers....I've owned the vehicle since new and I did not remove the 30 and put a 44 on it, it came from the factory that way.
