50 yrs ago, sure....It's one of many things you learn in automotive class. Along with tire rotation.
There's a lot of firsts the general public don't know about.
Think about it. Why would you keep driving and not maximize your tire wear. Every bump and pot hole you hit. Knocks your car out. And you all know that parts don't last forever. Including your steering components. Part of having an alignment is making sure your components are still tight. You don't get an accurate alignment with worn out parts.
If you want your car to last. It needs to be maintained. If you want your tires to last. They need to be aligned and rotated.
ONly problem with alignments. Tough to find a guy that knows what he's doing. As evidenced in one post on here with the guy who now has a crooked steering wheel and a alignment pull.
im sure the same class taught greasing the components
how many nipples on the car today?
