Question

When lubricating parts that do not have a grease relief port, inject grease until

A. The boot splits
B. Grease begins to escape from the base of the boot
C. The boot swells slightly
D. The part won't hold any more

Answer 1

C. The boot swells slightly

Step-by-step explanation:

Friction can be defined as a force that opposes the motion of an object in relation to another.

This ultimately implies that, friction is the opposition to the relative motion of two objects in contact. Therefore, lubrication (lubricants) are used to prevent friction between moving parts.

Generally, grease relief port are created by manufacturers of mechanical parts so as to prevent over-lubrication.

However, when lubricating parts that do not have a grease relief port, inject grease until the boot swells slightly so as to maintain the seal at the ball joints.
