Total questions: 20
Worksheet time: 10mins
When installing new differential clutches:
The clutches should be soaked in differential lubricant
The clutches should be assembled dry
Additive should not be used
The clutches are installed after the side gears
The spacers that were removed from under the differential ring gear carrier bearings will determine backlash when reinstalled.
True
False
Ring gear tooth pattern represents
Proper pinion bearing preload and torque
Proper side gear internal clearance
Proper ring gear runout
Proper contact between the ring and pinion gears
The ___________ is held on by a large nut that also sets the preload for the pinion gear on crush sleeve types.
Ring gear
Half-shaft component
Pinion companion flange
Axle bearing
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 housing and the differential case
Ring gear and the differential case/carrier
None of the above
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.
Backward
Vertical
Forward
Lateral
A differential is being overhauled Technician A says to inspect the ring gear for trueness with a ruler. Technician B says to inspect the the thrust washers for chipping and galling. Who is correct?
Tech A
Tech B
Both
Neither
Technician A says that when disassembling a differential case, it's good practice to first measure ring gear runout. Technician B says that when overhauling a differential, it's good practice to save the crush sleeve for reuse. Who is correct?
Tech A
Tech B
Both
Neither
The differential pinion rotates and drives the differential ring gear.
True
False
The forces on the pinion gear are tremendous in that the driveshaft, which is connected to it, transmits the power to all of the following EXCEPT:
Pinion gear
Ring gear
Axles and tires
Transfer case assembly
Which of the following is NOT a possible power transfer option for a driver to select in a vehicle equipped with a transfer case?
Select one:
Four-wheel drive high range
Rear-wheel drive mid-range
Two-wheel drive
Neutral
In all-wheel drive vehicles, only two of the wheels are normally powered, typically the rear wheels.
Select one:
True
False
Using ______ drive prevents excessive tire wear and possible damage to the drivelines or other 4WD drivetrain components.
Select one:
Four-wheel
Two-wheel
All-wheel
Rear-wheel
Because the _______ are locked together at the transfer case, the difference in speed cannot be absorbed in the transmission, and the drivelines can be subjected to torsional binding because they are forced to rotate at the same rate of speed.
Select one:
Front driveshafts
Rear driveshafts
Both
Neither
All-wheel drive vehicles are intended for lighter duty and are sometimes referred to as "_______."
Select one:
Suburban vehicles
Chameleons
Boulevard SUVs
Avenue SUVs
Newer designs in pickup trucks and SUVs use constant-velocity (CV) joint type front axles.
Select one:
True
False
Tech A says that when making a turn, the front wheels travel a greater distance than the rear wheels. Tech B says that in off-road conditions, differences in speed between the front and rear driveshafts can be absorbed through slippage of the tires on the ground. Who is correct?
Select one:
Tech A
Tech B
Both A and B
Neither A nor B
Technician A says that part-time 4WD does not use a transfer case. Technician B says that AWD vehicles can safely drive with all four wheels on pavement. Who is correct?
Select one:
Technician A
Technician B
Both A and B
Neither A nor B
Technician A says that some front differentials are operated by a vacuum motor. Technician B says that some front differentials are operated by electric motors. Who is correct?
Select one:
Technician A
Technician B
Both A and B
Neither A nor B
Each four-wheel drive type of driveshaft has a U-joint at each end to transmit the drive through varying angles.
Select one:
True
False
