Need help with bearing install

Im new to bakes and having an issue installing my rotors to the spindles.

II put the bearings back into the rotor and began to tighten down the nut and then I started to spin it, it would go smooth and then rough like it was scraping the spindle or something like that. I tried different stuff but I felt like im missing something in this installation process?

Heres what I did...

removed front nut and bearing
took off rotor
removed inner bearing by turning it sideways and then pulling it out. I believe that may be an indicator of a problem right? I read that you need to remove the seal for the bearing to come off, this one just popped out by turning it sideways.
cleaned grease
redid suspension
grease spindle and rotor and bearings
pushed the inner bearing back in and it seemed to just push right through after it made it pass the seal.
installed got grinding noise like it sometimes scrapes up against the spindle

bearings seem fine, no missing bearings and they still spin freely.

I did read my manual but its for my 68 dart. I believe these disc brakes are from a 73 duster.
