Hearing a knocking noise from your car can be unsettling, whether it’s a minor disturbance or the sign of something more serious. At TGPP-Autocare Stevenage, we frequently encounter this issue, and it’s important to get to the bottom of it quickly. In this post, we’ll go over the common causes of knocking sounds and explain what steps you should take next.
Knocking Sound When Accelerating
If your car knocks when you accelerate, it could be due to low oil pressure. This issue creates a tapping or knocking noise, signaling that your engine isn’t being lubricated as it should be. Another possibility is worn or broken engine mounts. When these mounts are no longer functioning correctly, your engine may move more than it should, causing it to knock against other parts of the car.
Both of these issues require professional attention. At TGPP-Autocare, our expert mechanics in Stevenage can quickly diagnose the problem and provide the necessary repairs to prevent further damage.
Knocking Noise When Driving Slowly
When you notice a knocking sound while driving at lower speeds, low engine oil levels could be the cause. Insufficient oil leads to increased friction inside the engine, often resulting in a tapping or knocking sound. A simple oil top-up may solve this issue, but if the noise persists, it’s crucial to have a professional inspection.
Alternatively, worn suspension parts such as bushes, ball joints, or bearings could also lead to knocking, particularly when driving over uneven surfaces. At TGPP-Autocare, we offer comprehensive suspension checks to help you get to the root of the problem.
Knocking Noise from the Engine Bay
If the knocking is coming from the engine bay, it’s often a sign of worn components like drive belts, pulleys, or engine mounts. These sounds can also indicate a more serious engine issue that requires immediate attention. Continuing to drive with these sounds could cause further damage, so it’s best to stop and have a mechanic examine the vehicle as soon as possible.
Key Parts That Can Cause Knocking Noises
Several car parts could be responsible for a knocking sound, and locating the exact source requires professional expertise. Common culprits include:
• Underneath the car: Steering rack, worn shocks/struts, ball joints, damaged exhaust pipe, anti-roll bar bushes, or drop links
• In the engine bay: Engine mounts, worn crankshaft pulley, or loose drive belts
Is It Safe to Drive with a Knocking Noise?
Driving with a persistent knocking sound can be dangerous, depending on the source of the noise. Since there’s a high chance it’s engine-related, it’s safer to have your vehicle checked before continuing to drive. Ignoring the sound could lead to costly repairs or permanent damage to your engine.
