Hold the tie rod and twist, lift it and notice if it moves? Hold the tire and move it rapidly like the car was turning right to left intermittently; check for a movement.is there any movement? Any movement signals replacement; Count the threads shown on your old tie rods; install the new using the same amount of threads shown; then go to alignment shop and get it aligned.
