You should be able to find examples on this forum - plenty of us have made that mistake!

Two ways I've found that work well:

1) Put grease on the balls to stick them to the nut, then gradually insert the retaining tube as you go to support them.
2) Put the biggest magnet you can find on the ballnut, so the balls stick to it in side. Carefully place them in the right place with something non-magnetic.
