When do you know your CV axle is bad?
One indicator that your car has a bad CV axle is when your car exhibits excessive vibrations that originate from the axle. You experience these too much vibrations when you speed up your car. These vibrations may be indicative of a damaged axle shaft or CV joint.
How many CV axles are there in a car?
It’s a shaft with constant-velocity (CV) joints that transfers the rotating torque to a drive wheel in a car. It might also be called a half shaft or drive shaft. A typical front-wheel drive car has two CV axles (CV shafts), one at each front wheel.
When does a cv shaft need to be replaced?
Excessive vibration from failing CV shafts can interfere with handling and ride characteristics, and the overall safety and comfort of the vehicle. Usually the CV axle will need to be replaced if it is damaged enough to cause vibrations. CV axles serve as the final link between the engine and the wheels.
What causes a cv shaft to vibrate while driving?
Another symptom of a bad CV axle is excessive vibrations from the axle while driving. If a CV joint or axle shaft is damaged in any way that affects its balance while rotating, it will cause the shaft to vibrate excessively while operating the vehicle.
Why do CV axles last a long time?
The flexible CV joints allow for a smooth power transfer due to their ability to move up and down with the suspension or side to side when turning your front wheels. CV axles can last a long time but will eventually wear out. Thankfully, they provide many warnings signs before a complete failure.
What are the rollers on a CV axle?
A typical inner CV joint has three rollers on a tripod (spider) that can slide inside the CV joint housing, so the CV axle can extend or contract as needed. Typical CV axle (shaft) of a front wheel drive car with a Rzeppa outer CV joint and closed tripod-style inner joint.
How often should I have my CV axle inspected?
Your CV axles are not a maintenance item, but they do require inspection at specific intervals. Check your owner’s manual for time and mileage intervals, or have the axles inspected at least once a year. If you begin to experience any of the above symptoms, contact your mechanic immediately.
What causes a CV axle to click when turning?
When CV axles become excessively worn, the joints will become loose and click when turning. The clicks may become louder or more pronounced during sharper and faster turns, and will be heard on the side with the faulty CV shaft.
What causes power loss on a CV axle?
These early front axles could not apply consistent torque to the wheels, leading to power loss. The most common problem for CV axles comes when you have cracked or loose CV boots. This can happen the joints on either side of the axle, but most commonly it happens with the outer CV joint.
Do you need to replace CV axles in pairs?
There is no need to replace CV axles in pairs as long as the other axles are in good condition. There are many aftermarket CV axles on the market, but it’s much smarter and safer to use either the factory part from the manufacturer or a replacement of equal quality. The cost to have your CV axle replaced or repaired can vary drastically.

What causes a CV axle to wear out?
The most common problem for CV axles comes when you have cracked or loose CV boots. This can happen the joints on either side of the axle, but most commonly it happens with the outer CV joint. Without the boot to hold the grease in and dirt out, the joint will lose its lubrication and wear out over time.

Why are CV axles used in front wheel drive vehicles?
This joint allows the axle to transfer torque from the engine to the wheels consistently, even when the joint is turned at an angle. CV axles were built as front wheel drive vehicles became more common. Front wheel drive vehicles originally used axles with a cross shaped metal pivot between two carriers like on four-wheel drive vehicles.
How does a CV axle transfer torque at an angle?
Put simply, it is an axle that can transfer torque at an angle thanks to CV (constant velocity) joints. What is a CV joint? It is a joint consisting of steel balls held in place by a cage.
One indicator that your car has a bad CV axle is when your car exhibits excessive vibrations that originate from the axle. You experience these too much vibrations when you speed up your car. These vibrations may be indicative of a damaged axle shaft or CV joint.
Where does the power from the CV axle come from?
One of the essential components of a vehicle is the Constant Velocity (CV) Axle. The CV axles transfer power to the wheels. The power, of course, comes from the transmission and differential of the vehicles. This transfer of power, in turn, makes it possible for the vehicle to drive forward. The CV axles have joints that are greased and flexible.
Where does the CV nut connect to the wheel?
The outer CV joint, however, connects to the wheel hub splines. It connects through an axle nut that is found in the rotor’s center. The CV joint gradually slides into the splines of the wheel hub, connecting the CV joint to the hub. The axle shaft, then, connects the outer and inner CV joints.
Why do front wheel drive vehicles have CV joints?
These flexible joints let the axle flex and adjust to the driving and road conditions. This flexing or adjustment has minimal effect on the delivery of power. Moreover, the majority of front-wheel drive vehicles have Constant Velocity (CV) Joints. Yet, you can also find the CV joints in some rear-drive vehicles.
