Why do Subaru bearings fail?

Why do Subaru bearings fail?
Subaru bearings can fail due to a variety of reasons. Here are some factors that can contribute to bearing failure in Subaru vehicles:
1. High radial and axial forces: When driving, the weight of the vehicle rests on the bearings, and the speed creates additional forces. Driving through curves can also generate axial forces. Additionally, impacts on uneven roads or potholes can put high stress on the bearings.
2. Contamination: Contamination can lead to premature bearing failure. Dust, dirt, water, and other contaminants can enter the bearing assembly and cause damage.
3. Poor maintenance: Lack of proper maintenance, such as failure to repack the bearings with grease or neglecting to replace worn-out bearings, can contribute to bearing failure.
4. Driving habits: Aggressive driving, such as rapid acceleration, hard braking, and taking corners at high speeds, can put extra strain on the bearings and contribute to their failure.
5. Aftermarket components: Some aftermarket companies refurbish wheel bearings, and if the quality of the refurbished bearings is not up to standard, it can lead to premature failure.
It’s important to note that these factors can vary depending on the specific model and year of the Subaru vehicle. Regular maintenance, including inspections and timely replacement of worn-out bearings, can help prevent premature bearing failure.
Please consult a qualified mechanic or Subaru service center for a more accurate diagnosis and advice specific to your Subaru vehicle.

What is the life expectancy of a wheel bearing?

approximately 85,000-100,000 miles
As mentioned previously, the average life of wheel bearings is approximately 85,000-100,000 miles. However, that lifespan can be shortened if you hit a curb, speed bump, or pothole at high speeds. Contamination from water, mud, road salt, or sand can also shorten the life of your wheel bearings.

Why do my wheel bearings keep wearing out?

Wheel bearings are especially vulnerable if you hit a pothole, a tall curb, or a speed bump at a brisk speed. If water, mud, road salt, or sand gets past the seal and touches the bearings, it will contaminate the grease, causing the bearings to wear down, eventually leading to failure prematurely.

Why do my bearings keep going bad?

The majority of bearing failures occur because of improper lubrication. Lubrication failure can occur if the wrong lubricant is used, if not enough lubricant is applied, or if the bearing has been exposed to excessive temperatures that have caused the lubricant to degrade. Corrosion & Contamination.

What is the main cause of wheel bearing failure?

Impact damage or poor road quality – all impacts from driving through a pothole, driving over speed bumps or hitting the curbstone can damage a wheel bearing and reduce its lifespan.

How do I know if my Subaru wheel bearings are bad?

So when you’re checking your wheel bearing the obvious thing to do first is Shake It. It feels nice and tight now I’ll spin. It. I do not hear nothing like I said earlier it sounded to me like it was

Can I drive with a bad wheel bearing?

Can I drive with a bad wheel bearing? No, it can be very dangerous. The bearings can cause a severe problem if they malfunction. As we said before, extreme heat can be caused by friction, and this can cause a sudden seize of the bearing, causing the wheel to get blocked at whatever speed we are driving at that moment.

Do Subarus have wheel bearing issues?

Subaru wheel bearing replacement is a common requirement especially for older Subaru models that don’t have the type 2 bearing design.

What are the first signs of bearing failure?

If your bearing is suddenly noisy during operation, you’re looking at a bearing failure. This excess noise is created when the raceways of the bearing have become damaged, causing the rolling elements to bounce or rattle during rotation.

What are the five cause of bearing failure?

10 Common Causes of Bearing Failure

• Lubrication Failure. If your bearings have failed, there’s a good chance it’s due to improper lubrication.
• Contamination.
• Misalignment.
• Improper Mounting.
• Corrosion.
• False Brinelling.
• Fluting (Electrical Damage)
• Spalling (Fatigue)

How much does a Subaru wheel bearing cost?

about $350
What’s the cost for wheel bearing replacement on my Subaru. For a national average across all vehicles, the average cost to replace the wheel bearings (for 1 wheel) is about $350 (including parts and labor).
