On 2008 and later models, the manufacturer advises that all suspension and steering system fasteners requiring specific torque should be replaced with new ones whenever removed, excluding subframe bolts. For Sedan and Coupe models, begin by opening the trunk or liftgate to remove the interior trim panel for access to the shock absorber top mounting nut. Use an Allen key to hold the piston rod while removing the upper mounting nut. Chock the front wheels, jack up the rear, and support it on axle stands before removing the wheels as needed. Place a jack under the lower suspension arm/coil spring for support, unscrew and remove the lower mounting bolt, then withdraw the shock absorber. For Wagon models, chock the front wheels, jack up the rear, and support it on axle stands before removing the wheels. Release the exhaust from the rubber hanger on the left-hand shock absorber, undo the rear exhaust muffler heat shield bolts, and remove it to access the upper shock mounting nut. Support the lower suspension arm/coil spring with a jack, unscrew and remove both the upper and lower mounting bolts, then withdraw the shock absorber. To test, check the mounting rubbers for damage; if worn, they may be replaceable separately from the shock absorber body. Mount the shock absorber in a vise by the lower mounting, examine for fluid leakage, and test operation through full and short strokes, ensuring resistance is smooth and continuous. For installation, reverse the removal procedure, tightening the mounting bolts to specified torque, and ensure the supporting jack can be adjusted as needed for shock absorber installation. Final tightening of the mounting bolts should occur with the vehicle weight on the wheels or by simulating normal ride height with the jack before tightening the fasteners to torque.
