Infiniti QX56 2004-2010 Suspension Specifications

The 2004-2010 Infiniti QX56 is compatible with various suspension components, including shock absorbers, struts, coil springs, and control arms. OEM parts are designed to meet the vehicle's specifications, but aftermarket options from reputable brands like Bilstein, KYB, and Monroe are also compatible. Ensure the parts are designed for the QX56's model year and trim to avoid fitment issues. Always verify compatibility with the manufacturer or supplier before purchase.

Regular maintenance of the suspension system includes inspecting shock absorbers, struts, and bushings every 30,000 miles or as recommended in the owner's manual. Look for signs of wear, such as leaking fluid, uneven tire wear, or excessive bouncing. Lubricate suspension components as needed and replace worn parts promptly. Wheel alignment should be checked annually or after hitting significant road hazards to ensure optimal performance and safety.

To replace the rear shock absorbers, first, secure the vehicle on a flat surface and lift it using a jack stand. Remove the rear wheels for better access. Locate the top and bottom mounting bolts of the shock absorber. Use a wrench to remove these bolts, then carefully detach the old shock. Install the new shock absorber, ensuring it is properly aligned, and tighten the mounting bolts to the manufacturer's torque specifications. Reinstall the wheels and lower the vehicle.

If your QX56’s suspension makes noise over bumps, start by inspecting the shock absorbers, struts, and bushings for signs of wear or damage. Worn components often cause clunking or squeaking noises. Check for loose bolts or nuts in the suspension system and tighten them if necessary. If the noise persists, consider having a professional mechanic perform a detailed inspection to identify and replace any faulty parts.

To optimize suspension performance, use high-quality components like performance shocks or coilovers designed for the QX56. Regularly inspect and maintain the suspension system to ensure all parts are in good condition. Adjust tire pressure to the manufacturer’s recommended levels and ensure proper wheel alignment. Avoid overloading the vehicle, as excessive weight can strain the suspension. Upgrading to a sport-tuned suspension kit can also enhance handling and ride quality.
