This sort of work should be unsigned to a competent, auto mechanic or service man. But it would not be amiss for the owner to know exactly what the service man has to do, and to see that it is dont properly.

In fact, the knowledge of what in to be done in lubricating a chassin will lead the motorist more to appreciate the importance of having this work done at regular intervals.
