Driveline Final

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

4WD AWD Both A&B

When two drive shaft yokes are in alignment with each other, they are considered:

In phase

What is the purpose of the ring and pinion in a conventional passenger vehicle?

It enables drive shaft torque to turn 90 degrees

In a conventional RWD vehicle, the engine and tranny are mounted:

Longitudinally @ the front

With a(n) __________, drive from the engine is transmitted to a rear axle assembly by a drive (propeller) shaft.

RWD layout

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

Shims

What is the max angle at which a U-joint is capable of properly working?

3 degrees

All of these are drivetrain components except?

Balance shafts

In some RWD vehicles, the rear U-joint connects directly to a(n):

Companion flange

Lug ____ are pressed into the axle flange and used to secure the wheel onto the vehicle.

Studs

TRUE or FALSE? Depending on the vehicle, the arrangement of the drivetrain assemblies can vary.

True

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

True

TRUE or FALSE? On FWD 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.

True

It is good practice to inspect the lug studs for _____.

All of the above

What is the purpose of the slip yoke on a drive shaft?

Allows for up and down movement of the suspension

The front section of the two-piece type drive shaft is supported at its rear end by a center bearing, called the _________.

Carrier bearing

The ___________ is a splined flange that transmits power to the pinion gear.

Companion flange

TRUE or FALSE? On every RWD vehicle, there is one drive shaft from the tranny to the final drive assembly and two axle shafts one from each side of the final drive to one of the rear wheels.

False

All of these apply to vehicles with live solid rear axles EXCEPT:

The struts absorb road shocks and bumps

In FWD layout, power is transmitted in a straight line from the engine through the ________ and out to the front axles (half-shafts).

Transmission Final drive (differential) gearing Both A&B

TRUE or FALSE? A drive shaft typically requires the use of joints to allow power to transfer smoothly as the drive shaft follows the movement of the suspension system.

True

TRUE or FALSE? A reason to use the two-piece style drive shaft is because the angle of the U-joint may be too great if the drive shaft were just a single piece.

True
