Motor Mounts: Engine Stability and Vibration Control
Mechanics throughout the region know INFINITI of South Bay has the best selection and price for buying genuine OEM parts. Your motor mounts secure your engine to the vehicle frame while absorbing vibrations that would otherwise shake the entire car. These rubber and metal assemblies allow for controlled engine movement during acceleration and braking while preventing excessive motion. Without functioning motor mounts, your engine would transmit harsh vibrations throughout the cabin and potentially damage surrounding components.
How Motor Mounts Reduce Engine Vibration
Your motor mounts use rubber or hydraulic fluid-filled chambers to isolate engine vibrations from the passenger compartment and chassis. Most vehicles use three or four mounts strategically positioned around the engine bay to distribute weight evenly. The rubber elements compress and expand to absorb normal engine movement while maintaining proper alignment. Advanced hydraulic mounts contain fluid chambers that provide better vibration dampening at idle speeds compared to solid rubber designs.
Mount Deterioration and Replacement Timing
Motor mounts typically last 60,000 to 100,000 miles before the rubber deteriorates from heat, oil exposure, and constant flexing motion. Failed mounts allow excessive engine movement that creates clunking noises during acceleration or gear changes. You may also notice increased cabin vibration at idle or visible engine movement when revving in park. The engine relies on secure mounting to prevent damage to connected components like hoses and wiring harnesses.
Genuine INFINITI Mounts Versus Generic Replacements
Genuine INFINITI motor mounts are engineered with specific rubber compounds and hydraulic fluid formulations designed for your engine's weight and vibration characteristics. Aftermarket mounts often use cheaper materials that fail prematurely or provide inadequate vibration isolation for comfortable driving. Models like the Q50 and QX60 require precise mount specifications that only genuine parts can deliver consistently over their service life. The vast inventory of genuine OEM parts here at INFINITI of South Bay includes all the components you need to keep your vehicle running great.
