Exam 40: Drive Axles and Differentials

Technician A says a double-offset plunging-style CV joint uses a cylindrical outer housing with straight grooves. Technician B says a double-offset plunging-style CV joint is a compact design. Who is correct?

CV joints provide ______.

Technician A says the differential allows torque to be transmitted to the driving axles at different speeds when the vehicle is turning a corner. Technician B says the gear ratio of the drive axle's ring and pinion gears provide a gear reduction and torque multiplication. Who is correct ?

A cyclic vibration that comes and goes between 45 and 60 mph (72 to 97 kph) is being discussed. Technician A says the problem may be caused by an out-of-balance tire and wheel. Technician B says the Rzeppa CV joint may be bad. Who is correct?

Which type of bearing is NOT used on semifloating axles?

The torsional damper that is sometimes attached to an axle shaft serves to balance the shaft.

A tripod-style CV joint is being discussed. Technician A says the outer housing is sometimes called a tulip. Technician B says the inner tripod is often called a spider. Who is correct?

A _____-type limited slip differential uses a set of helical gears to transfer torque from the wheel that is slipping to the wheel with traction.

The CV joints nearest the transaxle are called the ______ joints.

Identify the basic internal components within a fixed-style CV joint.

Describe the action of differential side gears when the vehicle is cornering.

The axles in a(n) ____________________ axle housing drive the wheel assemblies but do not support the weight of the vehicle.

A humming or growling noise in the front of the vehicle that changes with road speed could be caused by ______.

If a noise is heard while driving straight ahead but it ceases on turns in the same direction, what is the most likely cause?

In FWD applications, the outboard joint is a plunge joint.

Which of the following is NOT a function of the final drive in a rear axle?

Which type of CV joint has a flat design?

The three basic types of driving axle shafts used in RWD vehicles are the three-quarter floating axles, full-floating axles, and ____________________ axles.

Describe the function of a differential.

What does the term "constant velocity" mean?
