Is there a way to adjust the steering box to help eliminate some of the play?

The upper & lower ball joints were just replaced.

Any help is appreciated.

replace the idler arm first, thats the biggest cause of a sloppy front end in the GMs.

Thanks for the info guys. I will try these suggestions!
