What is the difference between a CV joint and an axle?

A CV joint is a joint in a drive axle (or at the end of it) which allows torque to be transmitted through a varying angle - for example, front wheel drive where the front wheels both steer and drive the car. An axle is a straight shaft, a CV joint is a JOINT.

Is axle and CV joints the same?

An axle actually consists of two CV joints. These joints allow the axle to transfer the engine's power to the drive wheels at a constant speed while accommodating any travel conditions, including the up and down motion of the suspension and cornering.

What is the difference between a CV joint and a front axle?

Front wheel drive vehicles use CV joints on the front axles. CV joints allow the axle to bend and change while accommodating the bounce of the wheels. The axle bears the weight of the vehicle while also being strong enough to sustain the forces from braking and accelerating.

Is a CV joint the same as an axle boot?

The part that simultaneously enables the axle to flex while transmitting the driving force is called a drive axle joint, and is also known as a constant velocity (or CV) joint. The CV Boot is a ribbed, rubber flexible boot that keeps water and dirt out of the joint and the special grease inside the joint.

Should I replace the CV joint or the whole axle?

CV joints and boots can be replaced individually, but most professional technicians and even do-it-yourselfers prefer to replace the whole halfshaft assembly with a remanufactured shaft.

Difference Between Bad and Good CV Axle

Should I replace my CV axle?

The metal components then won't smoothly slide against one another, but will rattle and clatter together, creating a clicking noise that gets faster and louder as you accelerate, or gets worse as your steering wheel turns. This is a sure sign that your CV axle needs to be replaced.

What are the signs of a bad CV joint?

How many CV axles does a car have?

Front Wheel Drive vehicles have two CV Axle Shafts, one connecting each of the front wheels to the transmission. All Wheel Drive vehicles have four CV Axle Shafts, two connecting the transmission to the front wheels, and two more connecting the rear differential to the rear wheels.

What happens if you don't replace CV axle?

The Constant Velocity is sealed by a boot. This boot may get damaged, and when this happens, the joint will wear out and eventually fail. If you drive a car with a damaged CV, the joint will disintegrate further, making driving impossible. You'll not be able to control the vehicle and may get involved in an accident.

What is a CV joint also called?

Constant velocity joints, better known as CV joints, are found at the ends of the drive shafts. They are essential to connecting the drive shafts to the transmission and wheels. Because of their function and location, these joints easily wear out over time.

What is another name for a CV axle?

A constant velocity (CV) axle, also known as a half shaft, takes power from the vehicle's transmission and differential and transfers it to the wheels, allowing the vehicle to drive forward.

What is axle joint?

The axle, also known as the CV assembly, is comprised of a series of universal joints and shafts engineered to enhance stability and handling while driving. Excessive vibration, particularly during acceleration is a clear indicator that the axle is in disrepair.

What are the two types of CV joints?

The two most commonly used types of CV joints are the ball-type and tripod-type. In front-wheel drive vehicles, ball-type CV joints are used on the outer side of the drive shafts (outer CV joints), while the tripod-type CV joints are mostly used on the inner side (inner CV joints).

Can you drive with bad CV joint?

The Constant Velocity is sealed by a boot. This boot may get damaged, and when this happens, the joint will wear out and eventually fail. If you drive a car with a damaged CV, the joint will disintegrate further, making driving impossible. You'll not be able to control the vehicle and may get involved in an accident.

Are CV joints only on FWD?

Constant Velocity or CV joints are used in most front wheel drive vehicles, many all-wheel drive vehicles and some rear wheel drive vehicles. A CV joint is a joint designed to transmit even power through a wide range of angles with minimum friction and internal play.

Can CV joint be repaired?

Unfortunately, broken CV joints are not repairable—only the CV joint boot is. If your CV joints ever fail completely, the car will suddenly not be able to accelerate, since it won't have the means to transfer torque to the drive shaft or the wheels.

What causes a CV axle to go bad?

Bad or damaged engine mounts will cause the cv axle to keep breaking, overloading vehicles beyond its capacity and stress the axles with large bumps and potholes also will damage the cv joint too. Another way drivers can put their CV parts at greater risk is by adding lift kits to their vehicle.

How long will a CV axle last?

CV axle boots last for quite some time (80,000 miles) and are not items needing periodic replacement. But you absolutely should inspect them at least once a year, or even more often on cars with high mileage. They are most affected by prolonged off-road driving or heavy use in transportation-industry conditions.

What is the price of CV axles?

On average, a single axle replacement costs between $300 and $1,500, depending on the type of vehicle and labor hours. The cost of parts ranges between $760 and $1,030, while labor cost is between $170.00 and $180.

How many axles does a car have?

In most cases, cars have two axles to rotate the wheels. Larger vehicles that carry more passengers and have more wheels may have more axles. It's easy to identify the number of axles that your car or any other vehicle has. Just look at your car from the side, then count the pairs of tires.

Which CV joint fails first?

Consequently, the right outer CV joint and boot are the first to go. Special tools that may be needed to replace a shaft include a hub puller to separate the outer CV joint from the steering knuckle and wheel bearing and/or a hydraulic press for older Asian car applications with press-fit wheel bearings.

What does a bad axle shaft sound like?

Clicking Sound

If you're hearing a clicking noise when you turn the wheel, it could be an indication that your cv axle shaft is going bad. The clicking noise is caused by the CV joint at the end of the cv axle shaft. As the cv joint wears down, it becomes less able to absorb shock and vibrations.
