Exam 123: Drive Axle Shafts and Cv Joints

A rear-wheel drive vehicle shudders or vibrates when first accelerating from a stop. The vibration is less noticeable at higher speeds. The most likely cause is ________.

Technician A says that some FWD vehicles use unequal length front drive shafts called half shafts. Technician B says that unequal length drive shafts may cause a pull during hard acceleration called torque steer. Which technician is correct?

Which driveshaft can be longer without the need for a center support bearing?

Which of the following should you know to get a correct replacement driveshaft?

The maximum allowable difference between the front and rear working angle of a drive shaft is ________.

Which of the following is NOT used as CV joint boot material?

Two technicians are discussing torque steer on a front wheel-drive vehicle. Technician A says that equal length drive axle shafts help reduce torque steer. Technician B says that equal drive axle shaft angles help reduce torque steer. Which technician is correct?

The outer CV joints used on front-wheel drive vehicles are ________.

This type of driveshaft joint is called a(an) ________.

Two technicians are discussing a dented driveshaft. Technician A says that it should be repaired. Technician B says it should be replaced. Which technician is correct?

A CV joint can operate at an angle of up to 40 degrees.

Drive axle shafts are also called ________.

Technician A says that engine torque is transmitted through the surface of the hollow driveshaft from the transmission to the rear differential in a RWD vehicle. Technician B says that a bent driveshaft on a RWD vehicle can cause a condition known as torque steer. Which technician is correct?

Technician A says that two U-joints are used on a driveshaft to prevent vibration. Technician B says that the more equal the U-joint angles, the less chance of driveshaft vibration. Which technician is correct?

The Rzeppa type joint is the most commonly used outer joint on FWD vehicles.

Small differences in driveshaft U-joint angles cause vibration ________.

What type of plunging joint is pictured here?

A dent in a prop shaft can cause damage that may result in failure when engine torque is applied.

Which series U-joint has the greatest torque capacity?
