Motor Mounts: Foundation of Smooth Operation

The INFINITI of Orland Park parts team knows what it takes to keep your vehicle running great. Motor mounts secure your sophisticated INFINITI engine while isolating vibrations from the passenger compartment. We understand how these engineered mounting systems contribute to the refined, quiet cabin experience that defines INFINITI luxury. When motor mounts deteriorate, you'll notice increased vibration, engine movement, and compromised ride quality that diminishes your driving pleasure.

Advanced Motor Mount Technology

INFINITI motor mounts use sophisticated rubber compounds and hydraulic dampening to absorb engine vibrations while maintaining precise engine positioning. These mounts handle the substantial torque output of INFINITI's powerful engines while preserving cabin quietness. Premium models like the Q50 and QX60 feature multiple mount locations strategically positioned to control engine movement during acceleration and braking. The mounting system works in harmony with engine components to deliver the smooth, refined power delivery that INFINITI owners expect from their luxury vehicles.

Mount Deterioration and Replacement Indicators

INFINITI motor mounts typically require replacement between 80,000 and 120,000 miles as hydraulic fluid leaks and rubber compounds harden with age and heat exposure. High-performance engines generate more stress on mounts, potentially reducing their lifespan. Warning signs include excessive vibration at idle, clunking during gear changes, or visible engine movement when revving. Aftermarket mounts often use standard rubber that cannot match INFINITI's specialized dampening characteristics. Genuine INFINITI motor mounts maintain the precise vibration isolation and engine positioning required to preserve your vehicle's luxury ride quality and long-term mechanical integrity.
