I absolutely zoned out on the obvious answer that the inner axle seals would not be the same for D30/D44 since the Rubicon shafts are 30 spline and a larger diameter requiring a slightly larger inner diameter on the seal vs. the smaller diameter 27 spline shafts of a Dana 30. I'm struggling finding the p/n for the Rubicon inner seals in the Mopar parts guide though, normally it's straight forward to find a p/n. I'll look again asap.
