The part that is MOST-Likely a type of constant velocity universal joint is the:

Which of the following parts is LEAST-Likely included in the driveline?

What is the function of the crush sleeve?

The pinion gear drives the ring gear.

Most passenger cars have a single driveshaft, but a vehicle with a longer wheel base will MOST-Likely have a:

The vibration caused by the speeding up and slowing down of the driveshaft can be canceled by putting two Cardan U-joints next to each other.

All of the following statements are true EXCEPT:

Replacement joints usually have a zerk fitting for lubrication after installation and during service.

While having a discussion, Technician A says that the purpose of a differential is to transfer power from the driveline to the wheels. Technician B says that it increases engine torque by providing a final drive gear reduction, usually of about 2.5 to 3.5 to 1. Who is correct?

What is the purpose of gear oils?

With a(n) ____________________ gearset, one pinion gear tooth will move around the ring gear until it has contacted each one of its teeth.

In a planetary gearset, the pinion gear is lower than the centerline of the ring gear.

What is the purpose of locking hubs?

Front-wheel-drive vehicles have a transaxle with two ____________________ that deliver power to the front wheels.

With a(n) ____________________, one pinion tooth will contact two or three different ring gear teeth during one revolution and two or three different teeth the next revolution. At the third revolution it will be back to the same teeth on the ring gear.

The side gears and differential pinions are called ____________________.

When a slip yoke is used with an automatic transmission, there is sometimes a seal that goes over the output shaft. What is its purpose?

In ____, power flows through the locked planetary gearset to the mainshaft and to the rear differential.
