That thread isn't going to help the OP. He says he has 35 spline axles (bigger diameter than stock) and he has 2.30 ID on the axle tubes which is much smaller than stock. My guess is that there isn't a seal that fits his combo which is why it doesn't have seals in it. The 2.30 ID seems a little small. Typical axles would be 3 inch OD with 0.250 wall so 2.500 ID.
