On 2015 and later models, remove the cowl panel. In the engine compartment, mark the relationship of one of the mounting studs to the body, then remove the four upper mounting nuts. Loosen the wheel lug nuts, raise the vehicle and support it securely on jack stands. Remove the wheel. Unbolt the brake hose bracket from the shock absorber. Remove the wheel speed sensor and detach the wiring harness by removing the clamp bracket bolt. On 2015 and later models, remove the stabilizer bar link nut and disconnect the link from the strut. Support the control arm with a floor jack and unscrew the nuts securing the strut to the steering knuckle, then tap the bolts out with a hammer. Only turn the nuts; the bolts have serrated shoulders, and to turn them could damage the steering knuckle. Use the floor jack to lower the knuckle to allow room to remove the shock absorber/coil spring assembly, but be careful not to over extend the inner CV joint. Check the shock body for leaking fluid, dents, cracks and other obvious damage which would warrant replacement. Check the coil spring for chips or cracks in the spring coating. Inspect the spring seat for cuts, hardness and general deterioration. If any undesirable conditions exist, proceed to the shock absorber/coil spring disassembly procedure. Guide the assembly up into the fenderwell, align the previously made match marks and insert the upper mounting studs through the holes in the body. Once the studs protrude, install the new nuts so the shock won't fall back through but don't tighten them yet. This is most easily accomplished with the help of an assistant, as the strut is quite heavy and awkward. Use the jack to position the steering knuckle and install the two lower mounting bolts and nuts, then tighten the nuts to the torque. Install the wheel and lug nuts, then lower the vehicle and tighten the lug nuts to the torque. Tighten the upper mounting nuts to the torque. Have the front end alignment checked, and if necessary, adjusted.

If signs of wear such as leaking fluid, loss of damping capability, or issues like sagging or cracked coil springs are observed in the front suspension shock absorber and coil springs, disassembly and necessary overhaul are recommended. The shock absorbers themselves cannot be serviced and should be replaced if found faulty, while the springs and related components can be individually replaced. To maintain balanced characteristics on both sides of the vehicle, it's advisable to replace components on both sides simultaneously. After removing the assembly from the vehicle, ensure it's free from external dirt without damaging the protective spring coating. Utilize coil spring compressor tools to fully engage and compress the spring until tension is relieved from the upper mount. Carefully hold the shock absorber piston rod with a wrench and unscrew the nut, avoiding the use of an impact wrench. Subsequently, remove the upper mount, spring, boot, bump stop, and lower spring seat. If a new spring is to be installed, release the original spring from the compressor; otherwise, it can remain in compression. Examine all components for wear or damage, replacing them as necessary. Check the shock for fluid leakage, inspect the piston rod for pitting, and assess the shock body for damage. Test the shock's operation by moving the piston through various strokes, ensuring smooth and continuous resistance; any signs of wear, damage, or uneven resistance necessitate replacement. To reassemble, install the lower spring seat, bump stop, and dust boot onto the shock absorber, followed by the spring and upper mount/upper seat, aligning the arrow or notch appropriately. With the spring compressed, install the rod nut, ensuring the ends of the spring fit into the recessed portion of the seats and maintaining the specified gap. Tighten the nut to the prescribed torque while keeping the position at both ends consistent. Finally, release the spring tension and reinstall the spring assembly in the vehicle.

For 2011 and later models, the removal steps include supporting the lower control arm with a floor jack, removing the rear knuckle, lowering the jack to extend the coil spring fully, and then removing the spring.
