I use 1/16" (1.5mm) max play at EACH pin in the steering link system. This means I will tolerate no more than 1/8" (3mm) total on each steering knuckle to cylinder pair of pins, bushings, and plates.
On the steering axle trunnion bushings I say not more than 3/32" (2.3mm) play up and down. At that amount of play the bushing is nearly worn away on the upper section (in the frame pocket).
Equally important on the steering axle is the amount of fore and aft play of the axle to frame fit.
The clearance there on Toyota trucks up to 3 ton capacity should be.028" (.7mm) or less. I usually fit up with the thickest spacers that I can get in there, even if it results in zero clearance initially.
Try to put half the spacer thickness on the front pin and half on the back pin.

Toyota calls out for Molybdenum Disulfide grease for the steer axle trunnion bushings and for the mast trunnion bushings.
How many techs are using multi purpose grease instead?
