Exam 5: Front Drive Axles Servicing Front Drive Axles

On an average, _____ outer joints are replaced for every inner joint replacement.

To combat the adverse effects of torque steer, manufacturers will limit the _____ of their engine to avoid severe torque steer.

The Rzeppa CV-joint contains ____ ball bearings.

What three methods are used to hold CV joints onto the axle shafts?

Technician A says the inner race of the Rzeppa CV-joint is connected to the drive axle. Technician B says the ball bearings rotate on a trunnion within the outer housing. Who is correct?

Explain the "full-floating type" of drive axle used in transaxles.

In the figure of an exploded view of a typical CV joint shown, name the parts indicated by the arrows.

What are two commonly used boot clamps on a CV joint?

Technician A says the amount of torque steer a vehicle is dependent on the length of the axle shafts. Technician B says a factor that affects torque steer is the amount of power the engine produces. Who is correct?

What is the term used to describe a condition in which the car tends to steer or pull in one direction as engine power is applied to the drive wheels?

Most automobiles use a fixed inboard type of CV joint for front-wheel drive.

The _____ assembly transmits torque from the engine and transmission to drive the vehicle's wheels.

Unequal drive axles have been found to deliver more torque to the wheel with the longer shaft.

What is the purpose of the CV joint?

Like the Rzeppa CV joint, the ____ uses six balls in a cage and inner and outer races.

Torque steer is more prominent on FWD vehicles with high-output engines.

What are Torque Steer Compensation (TSC) programs?

There are differences between front-wheel bearings on front-wheel drives and rear-wheel drives. Technician A says most front-wheel drive vehicles use one tapered roller bearing whereas rear-wheel drive vehicles use two. Technician B says most front-wheel drive vehicles use one-piece sealed bearing units. Who is correct?

Explain the difference between a Rzeppa CV joint and tripod CV-joint.

CV joints are called constant velocity joints because their rotational speed changes with the operational angle.
