When Your Engine Goes "Bang": The Costly Consequences of a "Spun Bearing"

Spun a bearing is a catastrophic engine failure that can leave you stranded on the side of the road and facing a hefty repair bill. This occurs when a bearing, which is a metal ring that allows moving parts to rotate smoothly, fails and spins out of control. The resulting friction can cause severe damage to the engine and its components.

Spun Bearing Symptoms	Consequences
Knocking or rattling noises	Engine damage
Loss of power	Overheating
Oil leaks	Seized engine

Spun Bearing Risk Factors	Preventive Measures
High engine speed	Use high-quality oil and filters
Low oil level	Check oil levels regularly
Overheating	Monitor coolant temperature
Worn or damaged bearings	Replace bearings as needed

Success Stories
