Exam 7: Differentials and Drive Axles

The main types of _____ are torque sensitive, speed sensitive, or mechanically locked.

Preload in bearings eliminates _____.

The differential case is mounted on _____ so that it is able to rotate independently of the drive axles.

What are the three types of ring and pinion gear sets?

What type of gearset allows the drive shaft to be positioned low in the vehicle because the final drive pinion gear centerline is below the ring gear centerline?

At least four bearings are found in all differentials: one over the drive pinion shaft with the other three supporting the differential case.

What is "one wheel peel?"

Geared, torque-sensitive mechanical limited-slip differentials use _____ gears which react to an increase or decrease in torque at one of two shafts.

A _____ gearset is one in which any one pinion tooth comes into contact with only some of the ring gear teeth. One revolution of the ring gear is required to achieve all possible gear tooth contact combinations.

Distinguish between an integral carrier housing and a removable carrier housing.

When engines are placed longitudinally in the car, they are said to have "north/south" placement.

RWD final drives normally use a hypoid ring and pinion gearset that turns the power-flow 45 degrees from the drive shaft to the drive axles.

The bearing of a _____ is located on the outside of the housing which places all of the vehicle's weight on the axle housing with no weight on the axle.

The teeth of a hypoid gear are _____, causing a wiping action when meshing.

Technician A says that there are three designs of axle shaft bearings: ball-type, straight roller, and C-type roller bearings. Technician B says that the three designs are: ball-type, straight roller, and tapered roller bearings.Who is correct?

A differential is needed between any two drive wheels, whether in a RWD, FWD, all-wheel drive (AWD), pr four-wheel drive (4WD).

Name the basic differential components indicated by arrows in the figure below.

_____ express the number of turns the drive gear makes compared to one turn of the driven gear it mates with.

In a ring gear and pinion gear set, the pinion is the larger drive gear and the ring gear is the smaller driven gear.

Based on their construction, axle housings can be divided into what two groups?
