I agree with @Horatio, it's probably the servo itself, the one in my radix was exactly how you explained your issue, worked perfectly fine just a lot of play inside the servo itself, swapped it out and all the excessive play is gone now
 
Free play on the steering can develop at a number of points. On mine, play developed in the hubs at the pillow balls - easily remedied by tightening the the pillow ball socket until the excessive play is removed.

The other area where play was affecting both geometry and steering was the upper arms/wishbones. These had to be shimmed. Care needs to be taken that there is no binding either and that the arms still fall under their own weight following the addition of any shims. Mine needed just under 1mm of shim.

If slop develops rapidly, this can indicate a loose ball - check before they fall off! 🤣

The servo saver spring is very weak. You can tighten it up, but the bottom line is: unless you tighten it up all the way, it gives all the time and makes the steering vague/unresponsive - especially when you're giving it full beanz.

There are threads here dedicated to the springs that are much better suited for this job.

Note the space between the coils affords saving action in the event of a tumble/knock etc - but has a much firmer rate affording much more positive steering.
Have you a link for the bigger servo saver spring?
