Sounds to me like your inboard bearing inner race didn't get seated properly against the face of the spindle. There should be a grease slinger/shield dohicky behind that inner race. Most of those slinger deals don't fit very well - they're loose on the spindle and will hang slight off center until you seat that inner race against it. The inboard id of that race has a radius chamffer on it that matches the radius at the root of the spindle. If that slinger isn't hanging just right it will interfere with that fit and won't allow that inner race to seat properly. I usually put a small dab of silicone on the back side of those slingers to help them stick in place, centered, until I can drive the inner bearing race up tight against it.
