a)

Axle shaft

b)

Output shaft

c)

Slip joint

d)

Companion flange

2.

U-joints are typically used on driveshafts because they generally need to accommodate only small angles, although some manufacturers use CV joints to provide a smoother ride, or on off-road vehicles that have been lifted and experience a greater amount of suspension travel.

a)

True

b)

False

3.

On a semi-floating axle vehicle, the axle flange is bolted to the housing, while the vehicle's weight is supported by the hub & bearing.

a)

True

b)

False

4.

The ___________ does not provide any drive capabilities and is used on the rear of front-wheel drive vehicles.

a)

Live axle

b)

Dead axle

c)

Drive axle

d)

None of the above

5.

On front-wheel drive vehicles with a transverse mounted transaxle assembly, there are two half-shafts (axles) one on each side of the transaxle to each of the front wheels.

a)

True

b)

False

6.

Which of the following axles uses a single roller bearing between the hub and the outside of the axle housing?

a)

Semi-floating axle

b)

Full floating axle

c)

Floating axle

d)

Three-quarter floating axle

7.

On the _________, there is a single roller bearing between the hub and the outside of the axle housing.

a)

Semi-floating axle

b)

Three-quarter floating axle

c)

Full-floating axle

d)

Drive axle

8.

_______ use combinations of driveshafts and half-shafts depending on if the axle shafts are independent or nonindependent.

a)

Four-wheel drive vehicles

b)

All-wheel drive vehicles

c)

Both A and B

d)

Neither A nor B

9.

A(n) ________ drive transaxle typically does not place the final drive directly in the center of the vehicle; because the final drive is bolted to the end of the transversely mounted engine, it is offset to one side.

a)

All-wheel

b)

Half-shaft

c)

Two-wheel

d)

Front-wheel

10.

In the ________ axle, the axle bearing is placed between the axle and the axle housing.

Select one:

a)

Straight

b)

Full-floating

c)

Dead

d)

Semi-floating

11.

It is always good practice to check runout on the drive axle flange when there is a customer concern of vehicle vibration.

a)

True

b)

False

12.

Provision is normally made for adjusting the alignment of a two-piece driveshaft assembly by using _______ under the carrier bearing.

Select one:

a)

U-joints

b)

Flanges

c)

Shims

d)

Driveshafts

13.

In all rear-wheel drive and four-wheel drive vehicles, engineers fit a CV joint to the front end of the driveshaft, which allows for an increase of angles of the shafts without creating vibration.

a)

True

b)

False

14.

In ________ axles, the axle bearing is placed on the outside of the axle housing.

a)

Straight

b)

Full-floating

c)

Dead

d)

Semi-floating

15.

While both can transfer torque through an angle, the U-joint can do so at a much greater angle than the CV joint, which is why it is used on front half-shafts to accommodate large steering angles.

a)

True

b)

False

16.

Worn axle bearings allow the axle shafts to move, and the axle shaft movement will wear the axle seals quickly and create ____ that the axle fluid can leak out of.
