Exam 40: Drive Axles and Differentials

Identify three main components of an FWD half shaft assembly.

Outer CV joint operating angles can be as high as 40 degrees.

Fixed-tripod-type CV joints are being discussed. Technician A says the fixed tripod joint cannot be removed from the drive shaft or disassembled because of the way it is manufactured. Technician B says the fixed tripod joint has less angular capability than a Rzeppa-type joint. Who is correct?

When the vehicle is turning left, ______.

What two conditions are usually the first symptoms to be noticed when a differential or drive axle shaft problem occurs?

If a drive axle shows signs of rubbing against the chassis, the vehicle should be checked for ______.

What is the difference between a fixed CV-joint and a plunge type joint?

Which type of joint is NOT a constant velocity type joint?

Differential gearsets are being discussed. Technician A says the inside bore of the side gears is splined and mates with splines on the ends of the axles. Technician B says the differential pinion gears and side gears are in constant mesh. Who is correct?

Which of the following describes the double Cardan universal joint?

A ring and pinion gearset that has ten teeth on the pinion gear and thirty teeth on the ring gear is a ______.

Driveshaft speed variation is being discussed. Technician A says the speed variations at the transmission yoke end of the driveshaft are canceled out by the speed variations at the pinion flange end. Technician B says the operating angles at each end must be equal for the speed variations to cancel each other out. Who is correct?

In a two-piece driveshaft, when the yokes are in the same plane, the joints are said to be in phase.

In RWD applications with IRS, the ______ CV joint is a plunge type.

Describe the four distinct modes the vehicle should be operated in during a road test when diagnosing final drive problems.

A(n) ____________________ is a flexible coupling located at each end of the drive shaft between the slip yoke and the pinion flange on the drive axle assembly.

A fixed-style CV joint may be referred to as a(n) ____________________ joint.

Fixed-style CV joints are typically located nearest the transaxle.

In a differential gearset, the side gears deliver torque to the pinion gears.

A removable-carrier axle housing is sometimes called a ____________________-type differential.
