AUT203 Week 9 Quiz Drivetrains Review

All of the following statements are true EXCEPT:

Select one:

• when lock is selected on a manually locking hub, it acts on a sleeve.

• the sleeve slides in and out to lock the two splined components together.

• freewheeling hubs disconnect the hubs from the axle shafts and prevent rotation of the front-wheel drive components.

• in a four-wheel drive range, the drive is transmitted from the transfer case to the transmission.

In four-wheel drive applications, which of the following components transfers the drive from the transfer case (torque splitter) to the final drive units at the front and rear axle assemblies?

Select one:

• Drive shafts

• Drive axle

• Electromagnetic clutch

• Vacuum motor
