Infiniti QX70 2014-2017 Suspension Specifications

The suspension system for the 2014-2017 Infiniti QX70 is specifically designed for this model and may not be fully compatible with other Infiniti vehicles. While some components may share similarities, the QX70’s unique chassis and weight distribution require tailored suspension parts. Always verify compatibility using the vehicle’s VIN or consult the manufacturer’s technical specifications before purchasing or installing parts.

Regular maintenance for the QX70 suspension system includes inspecting shock absorbers, struts, and bushings every 12,000-15,000 miles. Check for leaks, wear, or unusual noises. Wheel alignment should be performed annually or after significant impacts. Lubricate suspension joints as per the service manual. Replace worn components promptly to ensure optimal performance and safety. Adhering to the manufacturer’s maintenance schedule is crucial for longevity.

To replace the suspension struts on a QX70, first secure the vehicle on a lift and remove the wheels. Disconnect the sway bar link and brake line bracket. Unbolt the strut assembly from the steering knuckle and remove it from the vehicle. Compress the spring using a strut compressor tool, then replace the strut. Reassemble in reverse order, ensuring all bolts are torqued to factory specifications. A professional alignment is recommended afterward.

Common suspension issues in the QX70 include worn shock absorbers, noisy struts, and loose or damaged bushings. Uneven tire wear or a bumpy ride may indicate alignment problems. Diagnose by inspecting for leaks, cracks, or play in suspension components. Use a diagnostic tool to check for electronic suspension faults. Addressing these issues promptly can prevent further damage and ensure a smooth driving experience.

To optimize suspension performance, ensure all components are in good condition and properly lubricated. Upgrade to high-performance shocks or coilovers for enhanced handling. Maintain correct tire pressure and alignment for stability. Avoid overloading the vehicle, as it can strain the suspension system. Regularly inspect and replace worn parts to maintain optimal performance and ride comfort.
