Buick Envision 2016-2020 Suspension Specifications

The 2016-2020 Buick Envision features a MacPherson strut front suspension and a multi-link independent rear suspension. The system is compatible with 17-inch, 18-inch, or 20-inch wheels and tires, depending on the trim level. The front strut assembly includes a coil spring and shock absorber, while the rear suspension incorporates separate coil springs and shock absorbers. The suspension is tuned for a balance of comfort and handling, with a front stabilizer bar (23.8 mm) and a rear stabilizer bar (22.0 mm) for reduced body roll.

Regular maintenance of the suspension system includes inspecting the shocks, struts, and springs every 12,000 to 15,000 miles. Ensure the tire pressure is maintained at the recommended level (36 PSI front, 36 PSI rear) for optimal ride quality. Lubricate suspension components annually or as specified in the owner's manual. Replace worn-out ball joints, control arms, or bushings promptly to prevent further damage. Schedule a professional alignment every 6 months or 6,000 miles to maintain proper suspension geometry.

To replace a suspension component, raise the vehicle on a lift or jack stands and remove the wheel for access. Disconnect the negative battery cable to prevent any electrical system malfunctions. For struts or shocks, use a spring compressor to safely remove the spring. Replace the worn component with the new part, ensuring all bolts and nuts are tightened to the specified torque (e.g., 40-50 ft-lbs for control arm bolts). Reassemble in the reverse order of disassembly and test the vehicle for proper operation.

Common suspension issues include uneven tire wear, clunking noises, or a bouncy ride. Inspect the tires for wear patterns, which may indicate misalignment or worn components. Check for loose or damaged suspension parts, such as ball joints or bushings. Test the shocks by bouncing the vehicle; if it continues to oscillate, the shocks may need replacement. Use a scan tool to check for any stored fault codes in the suspension control module (if equipped). Address any fluid leaks from the shocks or struts promptly.

To optimize suspension performance, ensure proper tire inflation and alignment. Upgrade to high-performance shocks or struts for improved damping. Install aftermarket sway bars for reduced body roll during cornering. Consider coilover suspension kits for adjustable ride height and stiffness. Regularly clean and lubricate suspension components to reduce friction and wear. For enhanced stability, maintain a consistent tire type and size across all four wheels.
