A Subaru Impreza Owner's Guide to CV Axle Shafts (2009-2016)
Understand the clicking and vibrations from your Impreza and learn how to fix it right.
- A clicking noise when turning is the most common sign of a bad outer CV joint.
- Vibrations during acceleration often point to a failing inner CV joint.
- OEM axles offer the best quality but at a high cost; quality aftermarket axles provide a good value for most drivers.
- Inspect your CV boots for tears or leaks regularly to prevent premature axle failure.
Is Your Impreza Making Strange Noises? It Could Be the CV Axle.
If you've started to hear a rhythmic clicking or popping noise when you make tight turns in a parking lot, a bad CV axle is the most likely cause. This is the classic sign that the outer joint of the axle is worn out. Another common symptom is a vibration you can feel through the car when you accelerate. This often points to a problem with the inner CV joint. You might also find dark grease splattered on the inside of your wheel or in the wheel well, which means the protective rubber boot has torn. 🎬 Watch: A mechanic's guide to diagnosing a bad CV axle. A torn boot lets the special grease out and allows dirt and water in, which quickly destroys the joint.
Don't Ignore a Bad CV Axle
While you might be able to drive for a short time with a clicking axle, it's not safe. The joint can fail completely, which would cause a loss of power to that wheel and could leave you stranded. It's best to get it inspected and replaced as soon as you notice symptoms.
Choosing a Replacement: OEM vs. Aftermarket
When it's time to replace a CV axle on your Impreza, you have two main choices: Original Equipment Manufacturer (OEM) parts from Subaru or new aftermarket parts from brands like DSS or Surtrak.
- OEM Subaru Axles: These are the same parts your car was built with. They are widely considered to be the highest quality and most durable option, designed specifically for your vehicle's drivetrain. However, they are also the most expensive, often costing several hundred dollars per axle.
- New Aftermarket Axles: Aftermarket axles are a popular choice because they are much more affordable. Brands like DSS and Surtrak offer brand-new axles that are designed to fit and function like the original part. The quality of aftermarket parts can vary, with some owners reporting vibrations or shorter lifespans compared to OEM. However, for a daily-driven Impreza that isn't heavily modified or used for serious off-roading, a quality aftermarket axle can provide excellent value. Many owners have positive experiences with them, especially considering the significant cost savings.
A Note on Remanufactured Axles
Some stores sell "remanufactured" or "rebuilt" OEM axles. While this can be a good option, the quality depends entirely on the rebuilder. A common debate among Subaru owners is whether a high-quality new aftermarket axle is better than a poorly rebuilt original one. For simplicity and a reliable warranty, many owners choose new aftermarket parts.
Known Issues for 2009-2016 Subaru Impreza
For this specific generation of Impreza, there are no widespread recalls from the National Highway Traffic Safety Administration (NHTSA) for CV axle failure. Recalls for CV axle issues have been issued for other Subaru model years, but not for the 2009-2016 range. The most common issue remains the tearing of the rubber CV boot, which leads to joint failure from contamination and lack of grease. Regular inspection of these boots, especially in climates with harsh winters and road salt, can help you catch a small tear before it becomes a big problem.

Frequently Asked Questions
Can I just replace the torn boot?
Yes, you can buy a CV boot kit. However, this job is very messy and often requires special tools to disassemble the axle. If the joint has been clicking or making noise, it's already damaged, and just replacing the boot won't fix it. In most cases, it's faster and easier to replace the entire axle assembly.
Is the left front axle the same as the right front?
No, the front left (driver side) and front right (passenger side) axles are typically different lengths and have unique part numbers. The same is true for the rear axles. Always make sure you are ordering the correct part for the specific position on your vehicle.
How long does it take to replace a CV axle?
For a professional mechanic, it usually takes between 1 and 2 hours per axle. For a DIYer with the right tools, it can be done in an afternoon. It involves removing the wheel, axle nut, and separating the ball joint to get enough room to pull the axle out.
Do I need an alignment after replacing a CV axle?
It depends on the replacement method. If you have to unbolt the strut from the knuckle to get the axle out, you will definitely need an alignment. If you can get the axle out by only separating the lower ball joint, an alignment may not be strictly necessary, but it is always a good idea to have it checked.
