Also these tie rod ends turn the same way . You will need to take one side off to adjust .
That is why one side is 18 and the other 16 for ultra fine adjustment
If the two ends are different size threads, once your in the ballpark lengthwise, you shouldn’t have to remove an end to adjust. With the threads being different, as you turn the rod it changes the length. One turn on the 18 pitch thread moves the rod 0.055” and on the 16 pitch moves it 0.0625”. If you subtract one from the other, each turn moves the rod. 0.0075”. You do have to be in the ballpark though as 18 revolutions on the rod only yields you 0.135”, just over 1/8”!
