A knocking or pinging sound coming from your car can be alarming, especially if it gets louder under acceleration. Many drivers ask us, “Why is my car making a knocking noise in Marble Falls?”, and at Marble Falls Auto Center, we know this sound often points to engine or suspension issues that need quick attention.
Common Reasons Why My Car Is Making a Knocking Noise in Marble Falls
1. Engine Detonation (Spark Knock)When fuel combusts unevenly in the cylinders, it creates a sharp knocking sound. This may be caused by low-octane fuel, carbon buildup, or timing issues.
2. Worn Engine BearingsA deep knocking sound that gets worse with engine speed may indicate worn bearings. This is a serious problem that can lead to engine failure if ignored.
3. Suspension ProblemsIf the knocking happens when going over bumps, it could be due to worn struts, ball joints, or sway bar links.
4. Loose or Broken Engine MountsEngine mounts hold the motor in place. When they wear out, you may hear knocking or thumping, especially during acceleration or deceleration.
5. Exhaust System IssuesLoose exhaust components can rattle or knock against the undercarriage, creating a noise that mimics engine trouble.
How to Fix a Knocking Noise
At Marble Falls Auto Center, we perform a detailed inspection to track down the source of the knock. This includes checking the engine, fuel system, suspension, and exhaust.
Depending on the cause, repairs may range from using the correct fuel or cleaning carbon deposits to replacing suspension parts or repairing engine components.

A knocking noise can be an early warning of serious engine or suspension problems. Waiting too long can turn a simple fix into a major repair bill.
