CV axles are a crucial part of a vehicle’s drivetrain system that many drivers may not be familiar with. Simply put, they play a vital role in transmitting power from the transmission to the wheels while allowing for the suspension’s up-and-down movement. As a result, it helps your car maintain traction and control while it’s in motion.

You may wonder how many miles a CV axle can last before it needs replacement, how much it costs to fix, and when you may need to replace yours. Let’s dive in and answer these service-related questions.

What is a CV axle? 

The “CV” in CV axle stands for “constant velocity.” This part is responsible for transmitting power from the transmission to the wheels while allowing for the up-and-down movement of the suspension. The axles contain a flexible joint that allows the wheels to turn and move up and down, enabling the vehicle to maintain traction on the road.

How many miles can I drive before replacing my CV axle?

The lifespan of a CV axle varies depending on different factors, like the make and model of the vehicle, driving conditions, and maintenance. 

According to Fixd, a company that provides diagnostic and maintenance services, a CV axle can last anywhere from 70,000 to 130,000 miles. However, RepairPal suggests that a CV axle can last the lifetime of your vehicle. Remember to keep in mind that these are just estimates, and the actual lifespan can vary.

What are the signs of a failing axle?

If a CV axle fails, it can cause various problems, including vibration in one corner of your vehicle, clicking or popping sounds while turning or changing speeds, grease marks inside your wheel well, and difficulty steering. If you notice any of these warning symptoms, you will want to have it inspected and replaced as soon as possible. 

How much does it cost to replace it?

RepairPal says the average cost to replace a CV axle is between $938 and $1,069, including parts and labor. Fixd estimates the average price for replacing the part is between $809 to $1,074. However, this cost can vary depending on whether you go to a mechanic or take on the job from your garage. Plus, you will also want to consider your vehicle’s make and model and the repair shop’s location – if you decide to take your car to one.

Importance of maintaining a CV axle

A CV axle is a vital auto part. It’s a part of your drivetrain system that can last anywhere from 70,000 to 130,000 miles, depending on your make and model.
