The knuckle is back together and load preset adjusted. The ABS sensor is OUT. The birf is greased and the inner oil seal is in. I put in the axle with the birf flat up as per manual but when the widest part of the birf, near the AMS ring gets about 1" inside the knuckle I can go no further. Feels like the birf or axle is hitting on something but I just cant see what. Any ideas
