Toyota steering box leak near input shaft/ball check valve?

[Poseidon_Fab]

Finishing up the sas on my 3rd gen 4runner and have a leak coming from the ball/check valve? on the front side of the input shaft. Anyone know of anyways to fix this? I believe the box was dropped and it looks like the ball is sorta pushed in, not entirely sure. Anyhow I've attached a picture.

Thanks,
Phil
