AUT203 Drivetrains Week 6 Quiz Differentials

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
