Front wheel bearing issue

[DaveBPT]

Just replaced both front wheel bearings and races. Now am unable to replace hub enough to either remove the "wobble" from loose fit or to insert cotter key due to castle nut not going on far enough. I have checked the races and both inner and outer appear to be fully seated. Checked part number to verify correct parts. Visually inspected bearing in races. Any ideas on what else to check?

Thanks,

Dave
