Exam 40: Drive Axles and Differentials

Which CV joint test should be performed to determine whether the CV joint boot needs to be serviced?

Axle shafts with CV joints at each end are found on the ______.

Before servicing the rear U-joint, slip joint, or center bearing on a two-piece drive shaft, ______.

Technician A says a hunting gearset is one in which one drive pinion gear tooth contacts only certain ring gear teeth. Technician B says a partial nonhunting gearset is one in which one pinion tooth contacts only six ring gear teeth. Who is correct?

Technician A uses an impact wrench to tighten axle hub nuts. Technician B stakes the axle hub nuts after they are tightened to lock them in place. Who is correct?

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

Plunge-type CV joints allow the length of the axle assembly to change as the wheel travels up and down.

Constant velocity joints are used to transfer uniform torque at a constant speed, while operating through a wide range of angles.

A ____________ axle does not drive a vehicle. It merely supports the vehicle load and provides a mounting place for the wheels.

Outer CV joint operating angles can be as high as 40 degrees.

When the yokes at each end of a driveshaft are in the same plane, the joints are said to be in ___________________.

A ___________________ permits the effective length of the drive shaft to change with the movement of the rear suspension and drive axle assembly.

Which manufacturer does not currently offer electronically controlled rear differentials?

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 final drive gears in the drive axle assembly are sized to provide a gear speed increase and torque reduction.

Differential gearsets are being discussed. Technician A says the inside bore of the side gears is splined and mates with splines on the ends of the axles. Technician B says the differential pinion gears and side gears are in constant mesh. Who is correct?

Describe the function of a differential.

What does the term "constant velocity" mean?

CV joints are lubricated with ______.

Pinion gear depth is adjusted by ______.
