Hi,
When you say side to side play, do you mean when the wheels are off the ground there is play back and forth similar to what would be experienced with bad tie rods? If so, are both sides moving in sync? You indicated there is play in the steering (feels delayed), that could be the result of a worn or out of adjustment steering gear.
Take a look through this information for adjusting it. Let me know if this is something you are comfortable doing. Note: If there are no loose components (tie rods, ball joints, pitman arm, drag link and so on), then likely the play is the gear itself.

Also, check to see if there is excessive play in the intermediate steering shaft. The last two pics below show the universal type joints where they can develop play. The first is in the vehicle and the second is where it attached to the steering gear.
Let me know if this helps or if you have other questions.
Take care,
Joe
