Total questions: 30
Worksheet time: 15mins
With a(n) _____, drive from the engine is transmitted to a rear axle assembly by a drive (propeller) shaft.
Solid rear drive layout
All-wheel drive layout
Front-wheel drive layout
Rear-wheel drive layout
Vehicles with rear- or mid-mounted engines always use a transaxle in the rear of the vehicle and transfer the drive to the road wheels by external drive half-shafts.
Select one:
True
False
Transverse front-wheel drive layout designs eliminate the need to transfer power _____ degrees, as with a rear-wheel drive arrangement.
30
110
45
90
On a three-quarter floating axle vehicle, the axle flange is bolted to the housing and stabilizes the wheel horizontally, while the vehicle's weight is supported by the hub and the bearing.
True
False
Torque steer can be caused by:
unequal length half-shafts.
improperly torqued lug nuts.
an incorrectly torqued wheel hub.
a faulty steering shaft.
The purpose of axle seals is to ___________.
Contain the lubricating fluid in the final drive assembly
Prevent water intrusion
Seal contaminants out of the sealed cavity
All of the above
A reason to use the two-piece style driveshaft is because the angle of the U-joint may be too great if the driveshaft were just a single piece.
True
False
On all of the final drive assemblies manufactured today, the anti-lock brake system (ABS) wheel speed sensor is incorporated in them.
True
False
In a rear-drive vehicle, the ring gear is bolted to:
the pinion bearing.
the differential carrier.
rear frame.
the leaf spring shackles.
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.
A popping noise
A jerking movement
A growling noise
Vibration
In all states, the law requires an inspection of the brakes that involves removal of the tires to gain access to the brake system at least once a year.
True
False
The removal process for drive axle shafts is always the same, whether for integral or removable carriers.
True
False
Differential fluid leaks are always caused by a plugged breather or vent tube in the housing, which causes a pressure buildup within the housing.
True
False
Limited slip differential _______ can result from clutch parts that are worn; in some cases, changing the limited slip lubricating oil fixes the problem.
Select one:
Growling
Chattering
Squeaking
Both A and B
A contact pattern is made by using some type of ______ to make the pattern stand out.
Grease
Prussian blue marking compound
Both A and B
Neither A nor B
In a differential, side bearing preload limits the amount of ______ movement that the ring gear can travel, whereas backlash sets the closeness of the ring gear into the pinion gear.
Select one:
Backward
Vertical
Forward
Lateral
Any excessive differential ring gear runout could be the result of debris caught between the ________ that was present upon assembly of the unit.
Side gear and differential case
Differential case housing and the differential case
Ring gear and the differential case
None of the above
When installing any type of seal, it's a good practice to:
use the correct installer so you don't damage it.
leave part of the seal extending out of the bore.
scrape the edge of the seal so it will seal better.
put RTV on the sealing lip to ensure against leaks.
What is the purpose of the slip yoke on the driveshaft?
It allows for up-and-down movement of the suspension
It enables the driveshaft to accommodate worn u-joints
It allows for a change of driveshaft angle during turns
It enables the differential to work at different angles
All of these are drivetrain components EXCEPT?
Driveshafts
Balance Shafts
Final Drives
Drive Axles
In vehicles with an independent rear suspension, the final drive unit is mounted on the chassis frame, and drive is transferred to each road wheel through external driveshafts (half-shafts), which have flexible joints on each end.
True
False
All of these apply to vehicles with live solid rear axles EXCEPT:
the struts absorb road shocks and bumps.
there's a continuous change of distance between the output shaft and final drive pinion.
the drive shaft angle changes relative to its connections.
the final drive pinion nose angle changes when accelerating or braking.
A(n) __________________ is necessary to measure driveline runout.
Protractor
Dial Indicator
Vibration analyzer
Angle gauge
Tech A says that a driveshaft center bearing is used on a vehicle with a short driveshaft. Tech B says that a driveshaft center bearing has a rubber insert that can deteriorate. Who is correct?
Select one:
Tech A
Tech B
Both A and B
Neither A nor B
A transfer case is most often used in a(n):
front-wheel drive (FWD) vehicle
four-wheel drive (4WD) vehicle
rear-wheel drive (RWD) vehicle
vehicle with a dead axle.
______ transmits power to the front and rear drive axles at normal drive speed.
Four-wheel drive low range
Four-wheel drive high range
Two-wheel drive
Neutral
In all-wheel drive vehicles only two of the wheels are normally powered, typically the rear wheels.
True
False
Technician A says that in all-wheel-drive vehicles, locked differentials are used to ensure ease in driving around curves. Technician B says that a third set of differential gears is used to allow turning and driving into curves. Who is correct?
Select one:
Technician A
Technician B
Both A and B
Neither A nor B
Vacuum controls have rubber diaphragms in them, heat and moisture can cause them to deteriorate over time.
Select one:
True
False
Choose the correct statement:
Select one:
A transfer case is mounted to the front of the transmission.
Drive shafts are used to move power from the transfer case to the front and rear drive axles.
When making a turn, the rear wheels travel a greater distance than the front wheels.
The ring and pinion gears allow the front wheels to rotate at different speeds.
