you need to rotate the light bulbs in your tow vehicle too.
lol, is this a serious post? those springs will go millions of miles with no issues. The bigger issue with leaf springs is that they tend to sag over time, so storing the trailer on blocks where the wheels do not touch the ground (the springs are fully extended and unweighted), is something you could do for taking care of it. Still this is not necessary
In less than two years I had one sag and one break, a third one was off in center pin location. With cheap Chinese steel, this ain’t your fathers world. I bought replacements at a farm supply store.
