How To Know If Your Subaru CV Axle Is Failing
Constant velocity (CV) axles are essential components of your Subaru’s drivetrain. They transfer power from the transmission to the wheels while allowing for smooth movement and steering. Over time, CV axles wear out, leading to noticeable symptoms and potential drivetrain issues.
In this guide, we’ll cover:
- Common signs of a bad CV axle in Subaru vehicles
- What causes CV axles to fail
- How to diagnose a bad CV axle
- CV axle replacement cost in Subaru models

Common Signs Of A Bad CV Axle In Subaru Vehicles
A failing CV axle can cause serious drivetrain issues. Here are the most common symptoms:
- CV joint clicking Subaru - A clicking or popping noise when turning.
- Subaru CV axle noise - A humming, growling, or clunking sound while driving.
- Vibration while accelerating - The car shakes, especially when pressing the gas pedal.
- Grease leaking from the CV boot - Torn CV boots leak grease, leading to joint failure.
- Uneven tire wear - A failing CV axle can cause wheel hop, which in turn can damage tires.
- Loss of power to the wheels - In severe cases, a broken axle will prevent the car from moving.
If you notice any of these symptoms, it’s time to inspect and diagnose your CV axle.
What Causes CV Axles To Fail?
Several factors contribute to CV axle wear and failure:
- Normal wear and tear - The constant flexing and rotation wear down the joints.
- Torn CV boots - If the rubber boot protecting the joint tears, dirt and moisture cause rapid deterioration.
- Hard driving conditions - Off-roading, potholes, and aggressive acceleration put extra stress on the axles.
- Lack of lubrication - The CV joint requires grease for smooth operation. A torn boot lets grease escape, leading to excessive friction and failure.
How To Diagnose A Bad CV Axle
Wondering how to diagnose a bad CV axle in your Subaru? Follow these steps:
Step 1: Listen for Clicking Noises When Turning
- Drive at low speed and turn the steering wheel fully left and right.
- A clicking or popping noise suggests a worn-out CV joint.
Step 2: Check for Vibration While Driving
- If you feel a vibration that worsens with acceleration, the CV axle could be worn out or imbalanced.
Step 3: Inspect the CV Boots
- Look underneath your car at the rubber boots covering the CV joints.
- If you see cracks, tears, or grease leaks, the axle may fail soon.
Step 4: Perform a Manual CV Axle Test
- With the car safely lifted, grab the axle shaft and try to move it up and down.
- Excessive play or looseness indicates joint wear or failure.
If your CV axle shows these signs, it’s time for a replacement.
How Much Does It Cost To Replace A Subaru CV Axle?
The CV axle replacement cost for a Subaru varies based on the model and whether you choose OEM or aftermarket parts.
- OEM Subaru CV axle price: Around $400-$600 per axle.
- Labor costs: Typically $150-$300 at a repair shop.
- Total replacement cost: Around $550-$750 per axle.
DIY installation can save money, but it requires proper tools and mechanical knowledge.
Can You Drive With A Bad CV Axle In A Subaru?
Driving with a failing CV axle is risky. While a worn CV joint may last for a while, it can suddenly fail, leading to a loss of power or a dangerous breakdown. If you hear CV joint clicking or notice Subaru drivetrain issues, replace the axle as soon as possible.
