To run the bottom hole on the chub, you need to also move the plastic spacer from under the knuckle to the top of the knuckle. This'll move the axle down to clear your wheels. I'm not sure about this, but you may need a different ball stud for the top of the knuckle? Not sure if it'll have enough tread to screw into the top of the steering knuckle with the spacer on top...
