What Are the Consequences of Not Replacing Engine Mounts?
4 Answers
If damaged engine mounts are not replaced, symptoms such as car idling, body vibration, steering wheel shaking, and loud body resonance noises may occur. After replacement, the engine will run more smoothly and stably, providing a more comfortable driving experience. Below is an introduction to engine mounts: Eliminating Resonance: The engine generates certain vibrations during operation. Engine mounts contain rubber components that can eliminate the resonance produced by the engine. Pressure Reduction: Some mounts also feature hydraulic oil pressure reduction, serving the same primary purpose. If the mounts are damaged, the vibrations from the engine will cause the entire body to vibrate. Notes: Typically, there are three engine mounts fixed to the body frame. If one is damaged and not replaced promptly, it disrupts the balance, accelerating the damage to the other two.
The cost of not replacing engine mounts is really high. I just went through this - driving felt like sitting on a massage chair, with vibrations transmitting to the steering wheel. My hands would go numb on long drives, and the ride was uncomfortable. When vibrations increased, cabin noise became so loud I had to raise my voice to talk with passengers. Over time, parts fatigue and deform more easily - like exhaust pipe joints loosening and leaking, or driveshafts wearing out faster, making repairs complicated. If the mount completely cracks, engine displacement could jam the steering system, potentially causing loss of control at high speeds with accident risks. Don't delay - regular inspection and replacement ensures safety. The money saved isn't worth it compared to maintenance costs. After replacement, the car becomes quiet again and drives comfortably.
Car enthusiasts know that when the engine mount rubber ages and cracks, causing the damping to fail, engine vibration intensifies, sending shockwaves throughout the body and easily triggering a chain reaction. The risk of damage to adjacent components is high, such as transmission mount deformation or exhaust system leaks, leading to constant noise and increased fuel consumption. Long-term vibrations accelerate wear on bearings and water pumps, significantly reducing part lifespan. I once delayed replacing them, resulting in noise so loud it affected music listening, not to mention a slight increase in fuel consumption. Later tests showed a slight increase in engine displacement, worsening handling performance and making steering less responsive during cornering. Timely replacement of engine mounts protects the entire vehicle system, avoiding costly repairs of larger components—a simple action that extends overall vehicle health.
Neglecting engine mount replacement poses serious safety hazards. Excessive vibration may cause the bracket to fracture, leading to engine displacement that could jam the brake pedal or steering column, resulting in severe high-speed loss of control consequences. A friend's vehicle was involved in an accident due to this issue, costing over ten thousand in repairs and compensation. The vibrations also affect suspension structure, damaging chassis components and causing oil leaks or abnormal noises. Safety comes first—don't underestimate routine maintenance. Timely replacement prevents problems before they occur, ensuring more secure driving.
