Exploring the Functionality of CV Axles

The video tutorial provides a detailed explanation of a CV axle, its components, and how it functions in a front-wheel-drive car. It covers the disassembly process, focusing on the inner and outer CV joints, and explains their mechanics. The tutorial also offers tips on cleaning and maintaining the axle, highlighting the importance of grease and the role of various components like the tripod joint and needle bearings. The video concludes with reassembly instructions and maintenance advice to prevent premature wear and failure.

What allows the CV axle to have a high degree of articulation?

• The differential

• The axle itself

• The sliding tripod joint

• The transmission

How is grease removed from CV axles in the tutorial?

• Using a grease-cutting chemical

• By applying high-pressure water

• With the presenter's brother's old underwear

• Using a specialized cleaning solution

What is the purpose of the snap ring in a CV joint?

• To maintain the position of the needle bearings

• To secure the boot clamps

• To keep the bearings from falling out

• To hold the axle in place

How is the inner CV joint designed to move?

• It is fixed and does not allow for any movement

• It permits translational motion and a degree of angular movement

• It allows for rotational movement only

• It allows for vertical movement to absorb shocks

What is the primary function of a CV axle in a front-wheel drive car?

• To reduce the vehicle's speed

• To connect the wheel to the engine directly

• To link the wheel to the transmission differential

• To provide power to the rear wheels

Why is the CV axle called 'constant velocity'?

• Because it can rotate at variable speeds

• Because it maintains the same rotation speed regardless of angle

• Because it increases the vehicle's velocity

• Because it reduces the velocity during turns

What role do the ball bearings play in the outer CV joint?

• They lock the axle in place

• They allow the axle to extend and retract

• They reduce friction between the axle and the housing

• They enable the housing to rotate, turning the wheels

What is the purpose of the grooves inside the housing of the outer CV joint?

• To hold the snap ring in place

• To allow the ball bearings to move slightly up and down

• To increase the joint's flexibility

• To store extra grease for lubrication

What is the difference in grease consistency between the inner and outer CV shafts?

• Outer shaft grease is thicker

• Both use the same type of grease

• No grease is used in the inner shaft

• Inner shaft grease is thicker

What is a common cause of CV axle failure?

• Over-lubrication of the joints

• Cuts in the boots leading to contamination

• Use of the wrong type of grease

• Excessive tightening of the clamps
