Technician a says that load-carrying ball joints should always have some play in them. technician b says that follower ball joints should never have some play in them. who is correct?

a. technician a
b. technician b
c. both a and b
d. neither a nor b

The right answer is d.

Explanation:

The amount of play that a ball joint can have (if any) depends on the application of the joint itself and the suspension system. For each vehicle, the manufacturer must warn wich is the maximum tolerance of play. For some load-carrying ball joints, the amount of play should be minimum or null (like in some heavy-duty vehicles). Therefore technician A is wrong. In most cases in urban vehicles, it is acceptable some level of play for follower ball joints (these joints are normally unloaded). Therefore the technician B is also wrong. That means neither technicians A nor B statements are correct.
