Exam 6: Drive Shafts and Universal Joints Servicing Drive Shafts and Universal Joints

Name the parts indicated by arrows in this figure.

Because the drive shaft rotates at high speeds and at varying angles, what is required to reduce vibration?

The Spicer style, mechanic's style (aka Detroit/Saginaw style), and the Cleveland style are  styles of _____.

A drive shaft must smoothly transfer torque while rotating, changing length, and moving up and down.

The _____ is an assembly of one or two Universal joints connected to a shaft or tube used to transmit power from the transmission to the differential.

The drive shaft has a natural vibration frequency.

_____ occur when opposing operating angles of two Universal joints cancel the oscillations developed by the individual Universal joint.

Technician A says most drive shafts have a slip yoke and three universal joints. Technician B says a drive shaft may vibrate if the balance pads are missing off of the tube. Who is correct?

What two facts must be considered when designing a drive shaft?

What are the three types of drive shafts?

What is the relationship between the operating angle and the installation angle?

A _____ consists of two individual U-joints connected by a centering socket yoke and a center yoke that functions like a ball and socket.

Technician A says that balance pads should be checked when checking U-joints because they are sometimes missing. Technician B says that this is not necessary because the balance pads are firmly adhered. Who is correct?

The drive shaft is normally made of seamless steel or aluminum tubing with universal joint yokes at each end.

A drive shaft rotates at six to eight times the speed of the car's tires.

What term describes the rotational speed at which an object begins to vibrate as it turns?

Common causes of driveline vibration are bad CV joints.

What is a Universal joint and how does it operate?

What is another name for the Cardan Universal joint?

Technician A says the Universal joint has a center cross with machined arms. Technician B says it has bearing cups that contain a set of ball bearings. Who is correct?
