Wash behind your ears
When your mother used to tell you to wash your hands, brush
your teeth and be sure to wash behind your ears, she was trying to instill good
habits pf cleanliness. After all, good habits are what make things easier and more reliable.
The same holds true for installing wheels on highway trucks
and trailers. When you get into the habit of cleaning the mating surfaces, it’s
no longer hard work or an arduous task, it’s habit.
