The steering box itself works the same way and has the same adjustments for both power and manual boxes.
There has been discussion in the past of them needing the same center resistance, but I have not seen any documentation for what the factory specifies on the power boxes.
There are a few choices for what application the CPP steering box came out of. Do you know whicj one you have?
The easiest thing is to try adjusting it and see if you can make the play go away. If you can, then look for the spec on how tight it should be. If the play does not go away with adjustment, then the box is just bad and needs replaced.
