All You Need To Know About Subaru CV Axles
Your Subaru’s CV axles are comprised of an axle shaft and a CV joint. They are responsible for transferring power from the transmission to the wheels. Knowing how a CV axle works, what happens when it is failing, and how to maintain it can save you time and money. We cover everything you need to know about Subaru CV axles right here.
What Are The Signs Of A Bad CV Axle In My Subaru?
Indicators of a failing CV axle include:
- Clicking or popping noises when turning: This often signifies a worn CV joint.
- Grease on the inside edge of tires: A damaged or torn CV boot can leak grease, leading to joint contamination.
- Vibrations while driving: A damaged CV joint can cause your vehicle to vibrate, especially during acceleration or when turning.
These symptoms can last for a while before complete failure, but additional damage can be done to the suspension, tires, and transmission if left too long. In extreme cases, the CV axle may detach from the hub.
How Much Does It Cost To Replace A Subaru CV Axle?
The cost of replacing a CV axle in a Subaru can vary based on factors such as labor rates and parts pricing. On average, the total cost of one OEM axle assembly ranges from $300 to $800. An All-Wheel-Drive (AWD) Subaru typically has four CV axle assemblies. Find the latest parts and prices at Subaru Parts Plus.
In most cases, the CV joint will wear out first, and the axle may not be faulty. However, the CV axle and joints are sold in one assembly for most newer Subarus. The part costs more, but there are labor savings, so the total expense of solving the problem is similar.
How Do I Know If My Problem Is The CV Joint Or The CV Axle?
The CV joint is a component of the CV axle. Symptoms like clicking noises during turns or visible grease leakage typically point to a failing CV joint. Even if the issue is isolated to the joint, replacing the entire axle assembly is often recommended for reliability. If your CV axle fails or detaches, it will lead to a sudden loss of power, and a potentially dangerous breakdown and accident.
Can I Replace A Subaru Axle Myself? How About The CV Joint?
Replacing a CV axle is a labor-intensive task that requires mechanical expertise and specialized tools. While experienced DIY enthusiasts might attempt it, consulting a professional mechanic is advisable to ensure safety and proper installation.
It is possible to replace just the CV joint on certain older Subarus, but you would still have to strip down the axle and the job would require more labor time.
What Tools Do I Need To Replace A CV Axle On My Subaru?
If you have the necessary experience to replace your own CV axle, you will need the following tools to do the job:
- Floor jack and jack stands: To safely elevate and support the vehicle.
- Socket set and breaker bar: For loosening axle nuts.
- Pry bar: To detach the axle from the transmission.
- Torque wrench: Ensures bolts are tightened to manufacturer specifications.
What Is The Best CV Axle For My Subaru?
Opting for Original Equipment Manufacturer (OEM) CV axles is highly recommended. OEM parts ensure compatibility and durability and maintain your Subaru’s factory performance standards. Subaru Parts Plus offers a comprehensive selection of genuine Subaru CV axles backed by Subaru’s manufacturer warranty.
How Long Does It Take To Replace A CV Axle On A Subaru?
The time required for CV axle replacement varies but typically ranges between 2 to 3 hours, depending on the specific model and the technician's experience.
Will A Bad CV Axle Affect My Subaru’s AWD System?
Yes, a compromised CV axle can adversely impact your Subaru's All-Wheel Drive (AWD) system, leading to uneven power distribution and potential drivetrain damage. Addressing CV axle issues promptly will help prevent further damage to the rest of the drivetrain.
Do You Need Alignment After Replacing A CV Axle?
Generally, your Subaru will not require a wheel alignment after replacing a CV axle as long as the work is done correctly and no other suspension components are disturbed.
However, it's always a good idea to have the alignment checked as a precaution, especially if you notice any unusual handling or tire wear.
How Long Do Subaru CV Axles Last?
With proper maintenance, Subaru CV axles can last over 100,000 miles. Regular inspections are essential to ensure longevity. Replacing torn CV boots as well as avoiding aggressive driving and harsh off-road conditions will all help extend the life of your CV axles.
