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
