Question 1

This job is performed by the driveshafts, transfer cases, final drives, differentials, and drive axles.

Accepted Answer

These components are responsible for delivering torque to the appropriate wheels in a vehicle's drivetrain system.

Question 2

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

Accepted Answer

In a rear-wheel drive layout, the engine's power is transmitted to the rear axle assembly via a drive (propeller) shaft.

Question 3

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

Accepted Answer

Both four-wheel drive and all-wheel drive vehicles can use combinations of driveshafts and half-shafts, depending on whether the axle shafts are independent or nonindependent.

Question 4

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

Accepted Answer

The companion flange is a splined flange that connects to the pinion gear, transmitting power from the driveshaft to the differential.

Question 5

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

Accepted Answer

The rear end of the front section of a two-piece driveshaft is supported by a center bearing commonly referred to as a "Carrier bearing."

Question 6

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

Accepted Answer

Shims are used under the carrier bearing to adjust the alignment of a two-piece driveshaft assembly.

Question 7

In each revolution of a driveshaft, the velocity of the driveshaft yoke changes every ___ degrees due to the angles that the driveshafts are operating on.

Accepted Answer

The velocity of the driveshaft yoke changes every 90 degrees due to the universal joint's operation, which causes fluctuations in speed as the driveshaft rotates.

Question 8

A double Cardan joint is considered by most technicians to be a _____ under normal driveline angles.

Accepted Answer

A double Cardan joint is considered a type of constant velocity (CV) joint because it allows for smooth power transmission at varying angles, similar to other CV joints.

Question 9

The angle of the rear axle assembly companion flange should be _______ to the transmission output shaft.

Accepted Answer

The answer of The angle of the rear axle assembly...

Question 10

If the driveshaft parts are not marked during disassembly, then an out-of-phase condition could result, and _________ will occur even if the driveshaft is in balance.

Accepted Answer

An out-of-phase condition in a driveshaft can lead to vibration because the components are not aligned correctly, causing imbalance during rotation.

Question 11

Driveline angularity is critical to ensure ________ are working at their proper angle.

Accepted Answer

U-joints require proper driveline angularity to function correctly and avoid vibrations or premature wear.

Question 12

The ______ is subject to weather and the same abuses as a U-joint.

Accepted Answer

The center bearing is subject to weather and similar abuses as a U-joint because it is part of the drivetrain that supports the driveshaft, which is exposed to the elements and mechanical stresses.

Question 13

If the center support bearing is equipped with a grease zerk, it should be lubricated whenever a(n) __________ is performed.

Accepted Answer

The answer of If the center support bearing is equipped...

Question 14

If all differential repairs have been done properly, ______ should be within specifications.

Accepted Answer

Both runout and end play should be within specifications if all differential repairs have been done properly.

Question 15

All of these are drivetrain components EXCEPT:

Accepted Answer

Balance shafts are used to reduce engine vibrations and are not part of the drivetrain.

Question 16

In a conventional rear-wheel drive vehicle, the engine and transmission are mounted:

Accepted Answer

In a conventional rear-wheel drive vehicle, the engine and transmission are typically mounted longitudinally at the front to align with the driveshaft that transfers power to the rear wheels.

Question 17

Vehicles with independent rear suspension have:

Accepted Answer

Independent rear suspension allows each wheel to move independently, requiring driveshafts with flexible joints (CV joints) to accommodate the movement.

Question 18

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

Accepted Answer

The slip yoke allows for the up-and-down movement of the suspension by sliding in and out of the transmission or transfer case, accommodating changes in driveshaft length as the suspension moves.

Question 19

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

Accepted Answer

The ring and pinion gear set in a vehicle's differential allows the drive shaft's torque to be turned 90 degrees to drive the wheels, typically in rear-wheel drive vehicles.

Question 20

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

Accepted Answer

The answer of When two drive shaft yokes are in...
