I changed out my tie rods and replaced them. The new pair is of different color, one green and one black. The old pair is also one green and one black. I put the same color one to match. However, I look at the pair and I cannot see the difference between the right and left side. All I know the inside joint is normal thread but the outside joint is reverse thread but I cannot spot the difference.

Can someone enlighten me?

Should be left on one end and right on the other, so when you turn the center section both move in or out at the same time. To put it another way, when you turn the RHT clockwise, it should move in (shortening the link) and the LHT counterclockwise, it should move in.
