How to Tell if You Have Spun a Bearing Subaru: A Comprehensive Guide

Subaru vehicles are known for their durability and reliability, which is why they have become a popular choice among car enthusiasts. However, even the most well-maintained vehicles may encounter some issues over time, and one of the most common issues that Subaru owners face is a spun bearing.

A spun bearing can cause serious damage to your vehicle’s engine, which is why it’s crucial to identify the problem as soon as possible. In this article, we will discuss what a spun bearing is, the symptoms of a spun bearing, and what you can do to prevent it from happening.

Key Takeaways

  • A spun bearing is a serious engine issue that occurs when the bearing fails, causing the crankshaft to rub against the bearing surface.
  • Symptoms of a spun bearing include knocking sounds, low oil pressure, and engine overheating.
  • Regular maintenance and proper oil changes can help prevent a spun bearing from occurring.
  • If you suspect that you have a spun bearing, it’s important to address the issue as soon as possible to avoid further engine damage.

What is a Spun Bearing?

A bearing is a component in your engine that helps reduce friction between the moving parts. Over time, bearings can wear out and fail, causing serious damage to your engine. When a bearing fails, it can cause the crankshaft to rub against the bearing surface, which can lead to a spun bearing.

A spun bearing occurs when the bearing spins or slides out of position, causing the crankshaft to come into contact with the bearing surface. This can cause serious damage to your engine, including bent or broken connecting rods, damaged pistons, and even engine failure.

Symptoms of a Spun Bearing

If you suspect that you have a spun bearing, there are several symptoms that you should look out for. Here are some of the most common symptoms:

Knocking Sounds

One of the most obvious symptoms of a spun bearing is a knocking sound coming from your engine. The knocking sound may be more pronounced when you accelerate, and it may get louder as the engine RPMs increase. This is because the crankshaft is rubbing against the bearing surface, causing a knocking or banging sound.

Low Oil Pressure

Another symptom of a spun bearing is low oil pressure. When a bearing fails, it can cause oil to leak out of the engine, which can lead to low oil pressure. This can cause serious engine damage if not addressed promptly.

Engine Overheating

A spun bearing can also cause your engine to overheat. This is because the friction caused by the rubbing between the crankshaft and the bearing surface can generate heat, which can cause the engine to overheat.

Poor Performance

A spun bearing can also cause your engine to perform poorly. You may notice a decrease in acceleration, power, and overall performance.

How to Prevent a Spun Bearing

Preventing a spun bearing is crucial in maintaining the longevity of your vehicle’s engine. Here are some tips to help prevent a spun bearing from occurring:

Regular Maintenance

Regular maintenance is key in preventing a spun bearing. Be sure to follow your vehicle’s maintenance schedule and have your vehicle serviced by a certified mechanic.

Proper Oil Changes

Proper oil changes are also important in preventing a spun bearing. Be sure to use the recommended oil for your vehicle and change it regularly. Old, dirty oil can cause bearings to fail prematurely.

Watch for Warning Signs

Be sure to watch out for the symptoms of a spun bearing and address any issues promptly. This can help prevent further engine damage.

What to Do if You Suspect a Spun Bearing

If you suspect that you have a spun bearing, it’s important to address the issue as soon as possible. Here are some steps to take if you suspect a spun bearing:

  1. Stop driving your vehicle immediately.
  2. Have your vehicle towed to a certified mechanic.
  3. Have your mechanic diagnose the issue and provide a repair estimate.
  4. Consider the age and mileage of your vehicle before deciding on a repair.
