How do I know if my CV axle is bad on my Subaru Forester?
If you own a Subaru Forester, it's important to be aware of the signs of a bad CV (constant velocity) axle. A faulty CV axle can lead to costly repairs if left unchecked. In this article, we'll provide a detailed guide on how to recognize the symptoms of a bad CV axle on your Subaru Forester.
What is a CV Axle?
The CV axle, also known as a half-shaft, is a crucial component in your Subaru Forester's drivetrain. It transmits power from the transmission to the wheels, allowing them to rotate at different speeds when turning. The CV axle consists of a series of joints that allow for smooth, constant-velocity rotation, even when the wheels are turning at different angles.
Signs of a Bad CV Axle
Here are the most common signs that your Subaru Forester's CV axle may be failing:
- Clicking or popping noises: When the CV axle is worn or damaged, you may hear a clicking or popping sound, especially when turning or accelerating.
- Vibration or shaking: A bad CV axle can cause a noticeable vibration or shaking in the steering wheel or the entire vehicle.
- Grease leaks: If the CV axle's protective boot is cracked or damaged, you may see grease leaking from the joint.li>
- Difficulty turning: A worn CV axle can make it harder to turn the steering wheel, especially at low speeds.
- Uneven tire wear: If one of your Forester's CV axles is failing, it can cause uneven tire wear on that side of the vehicle.
If you notice any of these symptoms, it's important to have your Subaru Forester's CV axle inspected by a qualified mechanic as soon as possible to prevent further damage and costly repairs.
Diagnosing a Bad CV Axle
To diagnose a bad CV axle, a mechanic will typically perform a visual inspection and may also use a diagnostic tool to check for any trouble codes related to the axle. They may also test the axle's movement and check for any signs of wear or damage.
If a CV axle is found to be faulty, it will need to be replaced. This is a relatively straightforward repair, but it's important to use a high-quality replacement part to ensure the longevity of your Subaru Forester's drivetrain.
By being aware of the signs of a bad CV axle and addressing any issues promptly, you can help maintain the overall health and performance of your Subaru Forester.
Can a CV axle go bad without leaking?
Yes. When CV axles start to wear out, the process is gradual. They may start to make noise or cause a pulsed steering or clicking at slow, maneuvering speeds. You can often continue for a while if you do not make a sharp turn movements.
Can you still drive with a bad CV axle?
Driving with a broken CV axle is risky and should be avoided. It can lead to further damage and loss of control. If you must, limit it to a short distance at low speeds. For reliable lighting, choose Glo LED!
How to tell the difference between a bad wheel bearing and a bad CV joint?
To tell the difference between a bad wheel bearing and a bad CV joint, listen to the noise. If you hear a grinding, growling, or rumbling noise coming from the affected wheel, it's a bad wheel bearing. If you hear a clicking noise coming from the affected wheel when turning, it's a bad CV joint.
How do I know when my CV axle needs replacing?
3 Signs The CV Axles On Your Vehicle Need To Be Replaced
- 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.
- Grease On Inside Edge Of Front Tires.

How to test a CV axle by hand?
To check for excess play in the CV axle, hold onto the axle with two hands and try to move it up and down and side to side. If there is any movement, it could indicate a worn-out joint or a problem with the front wheel bearing.
How many hours does it take to replace a CV axle?
about 1.5 to 3 hours
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. You can replace just one axle if it is all that is required.
How do I know if my Subaru CV axle is bad?
The best way to diagnose a bad CV joint/axle is to drive very slowly and turn hard right and turn hard left. If there is clicking during those hard right and left turns but it goes away when going straight, the CV axle is bad.
What are the symptoms of a failing CV axle?
Some common symptoms of CV axle failure include:
- Clicking Sound When Turning.
- Clunking Sound on Acceleration or Deceleration.
- Grease Leakage.
- Vibration While Driving.
- Perform a Visual Inspection.
- Perform a Test Drive.
- Cost-effectiveness.
- Time and Labor Savings.
What is the life expectancy of a CV axle?
While CV axles typically have a long lifespan with some lasting more than 100,000 miles, they can fail for a few different reasons.
Are CV joints covered under a Subaru warranty?
And unlike other plans, Subaru's does not exclude wear and tear of covered components (e.g., low engine compression, or excess oil consumption due to worn engine components); consequential damage to other components (e.g., brake caliper repairs requiring new brake pads); struts and constant-velocity joints (even torn ...
