If the Pittman and idler arm are good... outside of the tie rods and or any steering shaft coupler issues...the steering box is probably worn out.
Or the steering box is loose on the K frame, or the steering box mount itself has cracked welds and moves when you turn the wheel. Or the toe is wrong, oe the ball joints are worn out, or the LCA bushings are toast, etc, etc.
A full inspection of the suspension would be necessary, since any play in the suspension or the steering could lead to what someone might describe as “sloppy” steering.
