Is the servo on the fritz??
That's probably because either your radio or the servo (or both) is crap (by design or use).
To take out the play you need to address the ballcup/balljoint slop, the bearing play, the axle play and so on. You can do it (I do), but as has been said, it's not necessary for everybody.
Once all the slop is out, a setup station can be very helpful, if only to tell you something is wrong with the car. For instance, you can find an unequal toe problem on the rear where it isn't adjustable and points to some underlying problem (chassis/hub carrier, etc).
