CV (constant velocity) axles are important parts of your car. They help transfer power from the engine to the wheels, even when you turn or drive over bumpy roads. Let’s break down what CV axles do, how to know if they’re worn out, and when to replace them.

What Are CV Axles?

CV axles are in many front-wheel and all-wheel-drive cars. Each axle has two joints—one near the transmission and one near the wheel. These joints help the axle flex and move as the car turns or the suspension goes up and down.

Rubber boots cover the joints and are filled with grease to keep the parts lubricated and protect them from dirt and water.

Signs of Worn or Bad CV Axles

Over time, CV axles can wear out. Here are some signs that they might be going bad:

1. Clicking or Popping Noises: If you hear clicking or popping when turning, especially sharp turns at slow speeds, your CV joint might be worn.
2. Vibrations While Driving: If you feel shaking in the steering wheel or car floor, your CV axle could be damaged.
3. Grease Leaks: Look for grease around the wheel or under your car. This may mean the CV boot is torn, which can lead to joint damage.
4. Knocking Sounds: A knocking noise when you speed up or slow down could be a sign of a bad CV joint.
5. Car Won’t Move: If the CV axle breaks completely, your car won’t move.

How to Check CV Axles

Regular checks can help catch problems early:

• Look for Damage: Check the CV boots for cracks, tears, or leaking grease.
• Test for Loose Parts: If your car is safely lifted, see if the axle moves too much or feels loose.
• 
  

When to Replace CV Axles

Replace a CV axle if you notice any of the signs above. CV axles usually last between 70,000 and 130,000 miles, but driving conditions can affect this.

Replacement Tips:

1. Buy Good Parts: Choose original parts or high-quality replacements.
2. Get Professional Help: Replacing a CV axle can be tricky. If you’re not sure how to do it, have a professional handle it.
3. Check Other Parts: While replacing the axle, inspect other parts like ball joints or control arms for wear.

Tips to Keep CV Axles Healthy

• Check CV Boots Often: Look at the CV boots regularly to catch small problems early.
• Be Careful with Sharp Turns: Avoid making sharp turns while pressing hard on the gas, as this can wear out the joints faster.
• Fix Leaks Quickly: If you see grease leaking, get it repaired right away.
