That's how you adjust the toe alignment, tighten the locking nut that's on the inner tie rod end
put inner tie rod end on the rack, tighten until snug, place lock pin in hole and tap with a hammer unless it's a screw, place boot back on the rack and clamp both ends. Thread on outter tie rid end the same ammount as it required to remove them, place pivot in the knuckle and put the nut on, tighten until snug, place new cotter pin thru the pivot and bend, repeat on other side,
Place steering wheel in center position
with wheels off the ground, eye-ball your toe alignemt with your rear wheels by standing in front of the vehicle looking toward the rear,you can use the center treads in the tires or the edge of the tire as a good guide, then go to your alignment shop and have it computer checked, most shops won't charge much just to check it
If you notice the tire not in line, roll the inner tie rod end either way to straighten it, and set locking nut, make sure you hold the rod with a wrench when you snug it or the alignment will move
good luck
