Infiniti G37 2009-2013 Suspension Specifications

The suspension system for the 2009-2013 Infiniti G37 is specifically designed for this model and may not be compatible with other Infiniti vehicles. It is essential to verify part numbers and specifications before attempting to use components in different models. Compatibility can vary due to differences in chassis design, weight distribution, and drivetrain configurations.

Regular maintenance of the suspension system includes inspecting shocks, struts, and bushings every 12,000 to 15,000 miles. Replace worn components as needed. Additionally, check alignment annually and after any major impact. Lubricate joints and linkages during oil changes. Proper maintenance ensures optimal performance and extends the lifespan of the suspension components.

To replace rear suspension struts, first, secure the vehicle on a lift or jack stands. Remove the wheels and disconnect the sway bar link. Unbolt the strut from the lower control arm and upper mount. Compress the spring using a spring compressor, then disassemble the strut assembly. Install the new strut, reassemble, and torque all bolts to factory specifications. Finally, reattach the sway bar link and wheels.

Common suspension issues include noises, uneven tire wear, and poor handling. Noises often result from worn bushings or loose components, which should be tightened or replaced. Uneven tire wear may indicate an alignment issue, requiring professional adjustment. Poor handling can stem from worn shocks or struts, which should be inspected and replaced if necessary.

To optimize suspension performance, ensure all components are in good condition and properly lubricated. Upgrade to high-performance shocks or coilovers for better handling. Maintain proper tire pressure and alignment. Consider installing a stiffer sway bar for reduced body roll. Regularly inspect and replace worn parts to maintain peak performance.
