400 EX Axle Nut Will NOT Slide over Axle!

Hello, I just replaced carrier bearings on my 2003 and now I can’t get the (new) axle nut over the axle far enough to install the clip. I had difficulty getting the old one off but didn’t think much of it. So I decided to get a whole new nut, locking nut, and sleeve since the old one was rough.
The sleeve and locking nut slide over no problem but the large nut just won’t go.

Do I have a bent axle? There was no wobbling or shaking prior to disassembly and I can’t see any damage??
