Anyone know if the inner axle seals for D44 are same as D30s, and the proper part number please? Some people suggest it's dealer only, hope that's not true.

Thank you

My bet is they are the same since the TJ's Dana 30 and Rubicon front Dana 44 axle tubes are the same. I'll verify that tomorrow afternoon if no one else does by then.

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.

Thank you Jerry. What I've found so far suggests National Seal 710863 is the correct part, if you can confirm or offer another thought, I'd appreciate that

The front D44 inner seal p/n's I came up with are
SKF 12579A (that'd be my personal choice)
USA Standard Gear USA30232

Those came from Rock Auto, I just cannot find the Mopar p/n's for the Rubicon's inner seals for the front axle shafts.
