9.75 spider gear fell out need help to put back in
 

I am working on a 2000 f-150. i was replaceing the axle bearing and my spider gear has shifted and I cant get the pin back in to the carrier. I have a limited slip differential. I can't seem to rotate the carrier and get the gears to line back up so that I can install the pin. Any help would be great. Im sure it is something simple I just dont know the trick to it. Thanks
