What is a CV axle on a Subaru?

What is a CV Axle on a Subaru?
A CV axle, or constant velocity axle, is a crucial component of a Subaru’s drivetrain system. It is responsible for transferring power from the transmission to the wheels while allowing for the up and down movement of the suspension. The CV axle consists of a shaft with two constant velocity joints, one at each end, which allows the axle to flex and articulate as the vehicle moves and the wheels turn. This design enables the axle to transmit power smoothly even at varying angles and during suspension movement, hence the name “constant velocity”.
Signs of a Bad CV Axle on a Subaru
Several signs indicate a failing CV axle on a Subaru. These include:
– Grease Leaking From CV Axle Boot: A damaged CV axle boot can lead to grease leaking from the boot, which may be visible on the inside edge of the front tires and wheels, as well as on brake components and other nearby parts.
– Clicking Noise When Turning: A loud clicking sound coming from the front wheels, particularly when turning, is a common sign of a failed CV axle.
– Vibrations While Driving: Intense vibrations while driving can also indicate a problem with the CV axle.
Importance of CV Axle and Replacement Costs
The CV axle is crucial for enabling the front wheels of a Subaru to receive power and turn as the vehicle steers. When a CV axle fails, it can lead to significant issues such as grease leakage and vibrations, necessitating replacement. The cost of replacing a Subaru Outback CV axle/shaft assembly can vary depending on the specific model and the location, with an average cost of around $244 for parts and $95 for labor.
In summary, the CV axle is a vital component of a Subaru’s drivetrain system, responsible for transferring power from the transmission to the wheels while allowing for smooth articulation and movement. It’s important to be aware of the signs of a failing CV axle and the associated replacement costs to ensure the proper maintenance of a Subaru vehicle.

What are the symptoms of a broken CV axle?

Sound. Especially when turning grease splatter on undercarriage. The CV boot covers the joint on the axle. And contains the necessary grease to maintain the joint’s.

Can I drive if my CV axle is bad?

The Constant Velocity is sealed by a boot. This boot may get damaged, and when this happens, the joint will wear out and eventually fail. If you drive a car with a damaged CV, the joint will disintegrate further, making driving impossible. You’ll not be able to control the vehicle and may get involved in an accident.

What causes a CV axle to fail?

Bad or damaged engine mounts will cause the cv axle to keep breaking, overloading vehicles beyond its capacity and stress the axles with large bumps and potholes also will damage the cv joint too. Another way drivers can put their CV parts at greater risk is by adding lift kits to their vehicle.

Are CV axles easy to fix?

You absolutely can replace your CV axle at home, but you’ll need to be at least remotely comfortable using a jack, jack stands, and power tools. Assuming you have most of the equipment already set up in your garage at home, the cost to replace your CV axle will be quite reasonable.

Will a car move if the CV axle is broken?

Vehicle Will Not Move
Since the CV axles deliver engine power to the front wheels, If one of your CV axles has utterly and completely failed, the vehicle might not move at all.

How long do CV axles last Subaru?

The lifespan of your CV axle is typically fairly long, withstanding 80,000 to 100,000 miles under regular driving conditions. If you begin hearing a loud, rhythmic clicking noise as you turn, it’s a good sign the axle is failing.

How do I know if my Subaru CV axle is bad?

But I don’t get much noise but then if I turn. It. You hear that Rumble. And feel that Rumble that’s the u-joints. Trying not to break in half. So. If when you’re driving straight.

What causes a CV axle to go bad?

Bad or damaged engine mounts will cause the cv axle to keep breaking, overloading vehicles beyond its capacity and stress the axles with large bumps and potholes also will damage the cv joint too. Another way drivers can put their CV parts at greater risk is by adding lift kits to their vehicle.

How much does it cost to replace a CV axle on a Subaru?

The cost of parts ranges between $760 and $1,030, while labor cost is between $170.00 and $180. Replacing a single axle usually takes about 1.5 to 3 hours, so replacing all four others can take up to 12 hours, which increases the cost if you factor in both parts and labor. However, replacing all four axles is optional.
