How long do Subaru axles last?
Subaru vehicles are known for their durability and reliability, but like any car, they require regular maintenance to keep them running smoothly. One common question Subaru owners ask is: how long do the axles last? In this article, we’ll explore the lifespan of Subaru axles, factors that affect their longevity, and tips to extend their life.
Understanding the Role of Axles in Your Subaru
The axles in your Subaru are a critical component of the drivetrain. They transfer power from the transmission to the wheels, enabling your car to move. Subaru vehicles, particularly those with all-wheel drive (AWD), rely heavily on their axles to maintain traction and stability in various driving conditions. Because of this, the axles are subject to significant wear and tear over time.
Typical Lifespan of Subaru Axles
On average, Subaru axles can last anywhere from 50,000 to 100,000 miles. However, this range can vary depending on several factors, including driving habits, road conditions, and maintenance practices. For example, if you frequently drive on rough terrain or in areas with harsh weather conditions, your axles may wear out more quickly.
Factors That Affect Axle Longevity
Several factors can influence how long your Subaru axles last. Here are the most common ones:
- Driving Habits: Aggressive driving, such as hard acceleration and sudden braking, can put extra stress on the axles.
- Road Conditions: Driving on uneven or poorly maintained roads can accelerate axle wear.
- Weather Exposure: Salt and moisture from winter roads can lead to rust and corrosion, which may weaken the axles over time.
- Maintenance: Regular inspections and timely replacement of damaged CV boots (which protect the axle joints) can significantly extend the life of your axles.
Signs Your Subaru Axles May Need Replacement
It’s important to recognize the warning signs of axle wear to avoid further damage to your vehicle. Here are some common symptoms:
- Clicking Noises: A clicking sound when turning is often a sign of a failing CV joint, which is part of the axle assembly.
- Vibrations: Excessive vibrations while driving, especially during acceleration, can indicate a damaged axle.
- Grease Leaks: If you notice grease around your tires or undercarriage, it could mean a CV boot has torn, exposing the axle to damage.
- Difficulty Steering: A damaged axle can affect your car’s handling and make steering more difficult.
Tips to Extend the Life of Your Subaru Axles
To maximize the lifespan of your Subaru axles, follow these maintenance tips:
- Inspect CV Boots Regularly: Check for cracks or tears in the CV boots and replace them as needed to prevent axle damage.
- Drive Smoothly: Avoid aggressive driving habits that can put unnecessary stress on the axles.
- Keep Your Car Clean: Wash your car regularly, especially during winter, to remove salt and debris that can cause corrosion.
- Schedule Routine Maintenance: Have your axles inspected during regular service appointments to catch potential issues early.
Conclusion
Subaru axles are built to last, but their longevity depends on how well they are maintained and the conditions they are exposed to. By driving responsibly, keeping up with regular maintenance, and addressing issues promptly, you can ensure your axles remain in good condition for many miles to come. If you suspect a problem with your axles, don’t hesitate to bring your Subaru to a trusted auto repair shop like Kevin’s Autos for a professional inspection and repair.
Frequently Asked Questions
How many miles should an axle last?
Although many cars will get more than 100,000 miles on a CV axle and many will last much longer, it's possible for one to fail sooner too.
How long do Subaru ball joints last?
While ball joints may last 70,000 miles or more, they don't last forever. Their actual lifespan will depend on your driving habits, road conditions and exposure to road splash and salt.
How expensive is replacing an axle?
On average, replacing one is around $880, and $959 for an axle shaft. Repairing a front axle is about $550-$740, with the rear one approaching $480-$550.
Are axles expensive to replace?
Replacement axle shafts can be bought for between $60-150.00 each, and labor is generally between 1.5-3 hours to replace, bringing labor to around $150-350.00.
How do I know if my Subaru axle is bad?
Clicking Noise When Turning Sharply
The faster the vehicle is traveling, the more rapid the noise will be. If this noise only appears when the wheel is turned all the way in one direction, a bad CV axle is likely to blame.
How do I know if my axle needs replacing?
Bad vehicle vibrations after a collision with a bad pothole, unexpected curb, or other objects may indicate axle damage. Vibrations may be accompanied by an unusual rumbling noise underneath the vehicle, strange tire wobbling, or sluggish driving and steering, which may indicate a bent axle.
How long do Subaru bushings last?
They usually last between 90K and 100K miles. Yet, they can fail any time.
How often do axles need to be replaced?
Many mechanics recommend replacing CV axles between 80,000 and 100,000 miles. However, it really depends on driving conditions and maintenance history.
What causes axles to go bad?
A common cause of CV axle failure is a rupture to the boot. When the boot ruptures, the CV axle loses grease and is no longer lubricated. In addition, the tear can allow water and debris to get in the boot making it susceptible to premature failure.
How do you know if your ball joints are bad on a Subaru?
Signs Of A Bad Ball Joint
If you experience any of the following signs, chances are you have at least one bad ball joint: Clunking, squeaking, or creaking noise coming from the wheel area. Misalignment.
