How do I know if my Subaru CV axle is bad?
If you own a Subaru, it's important to be aware of the condition of your constant velocity (CV) axles. A bad CV axle can lead to serious issues with your vehicle's performance and safety. In this article, we'll explore the signs of a failing CV axle and provide guidance on how to determine if yours needs replacement.
What is a CV Axle?
A CV axle, also known as a constant velocity joint, is a crucial component in your Subaru's drivetrain. It connects the wheel hub to the differential, allowing the wheels to rotate at different speeds while transmitting power from the engine to the wheels. CV axles are designed to withstand the constant flexing and twisting that occurs during normal driving conditions.
Signs of a Bad CV Axle
There are several common symptoms that may indicate a problem with your Subaru's CV axle:
- Clicking or popping noises: As the CV axle begins to wear, you may hear a clicking or popping sound, especially when turning or accelerating.
- Vibration or shaking: A damaged CV axle can cause a noticeable vibration or shaking in the steering wheel or throughout the vehicle.
- Grease leaks: If the CV axle's protective boot is cracked or damaged, the grease inside may start to leak out, leading to further damage.li>
- Difficulty turning: A worn CV axle can make it harder to turn the steering wheel, especially at low speeds.
If you notice any of these signs, it's important to have your Subaru inspected by a qualified mechanic as soon as possible to determine the cause and prevent further damage.
Diagnosing a Bad CV Axle
To diagnose a bad CV axle, a mechanic will typically perform a visual inspection and may also conduct a test drive to observe the vehicle's behavior. They may also use a diagnostic tool to check for any trouble codes related to the CV axle or drivetrain. If a problem is identified, the mechanic will likely recommend replacing the affected CV axle.
Replacing a CV Axle
Replacing a CV axle is a relatively straightforward repair, but it's important to have it done by a qualified mechanic. Attempting to do it yourself without the proper tools and expertise can be dangerous and may lead to further damage to your vehicle. The cost of a CV axle replacement can vary depending on your Subaru model and the specific parts needed, but it's generally a relatively affordable repair.
By being aware of the signs of a bad CV axle and addressing any issues promptly, you can help ensure the continued safe and reliable operation of your Subaru.
How long do CV axles last on a Subaru?
80,000 to 100,000 miles
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 long does it take a mechanic to replace a CV axle?
1.5-3 hours
Labor rates vary from shop to shop but normally it will take 1.5-3 hours to replace a CV axle depending on the make and model of the vehicle. The total labor cost will depend on how many axles you are getting replaced.
What is the average cost of replacing CV axle?
On average, a single axle replacement costs between $300 and $1,500, depending on the type of vehicle and labor hours. The cost of parts ranges between $760 and $1,030, while labor cost is between $170.00 and $180.
When replacing CV axles, what else should I replace?
Wheel bearings, ball joints, tie rods ends, shocks, wheel studs, are all big tickets. Also gearbox seals. There is so much “while you're in there,” when replacing axles you'll run out of money before suggestions lol.
What is the life expectancy of a CV axle?
100,000 miles
While CV axles typically have a long lifespan with some lasting more than 100,000 miles, they can fail for a few different reasons.
What are the symptoms of a worn CV axle?
4 Signs of a Bad CV Axle/Half Shaft
- "Clicking" Noises When Turning.
- A Knocking Sound.
- Grease on the Inside or Edge of the Tires.
- Vibration While Driving. This is a tricky one, since there are many things that could cause vibration when you drive.
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.
Should I replace both CV axles if one is bad?
Many mechanics recommend changing both left and right CV axles simultaneously once one goes bad. The reasoning is that both axles have similar miles, wear, and working conditions. So, if one joint has failed already, chances are the other side isn't far behind.
How to tell if a 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.
Can I still drive with a bad CV axle?
Driving on a bad CV axle shaft can cause further damage to your vehicle and could even lead to an accident, as it's a structural part, like struts, that can lead to immediate, huge repairs if left unrepaired.
