You can Select Your Vehicle to check if 21018785 fits your vehicle.

To start with, loosen the driveaxle/hub nut and wheel lug nuts, raise the vehicle and support it on jackstands. Then remove the brake caliper and support it with a piece of wire, remove the caliper mounting bracket and brake disc. If equipped with ABS, remove the wheel speed sensor. Afterward, mark the strut to the steering knuckle; then loosen but not remove the strut-to-steering knuckle bolts. Thereafter separate the tie-rod end from the steering knuckle arm under which is positioned a balljoint-to-steering knuckle pinch bolt that you should remove so as to separate the balljoint. The next step is removing the driveaxle/hub nut and push out driveaxle from hub supporting it with wire. At this point remove strut-to-knuckle bolts by carefully separating steering knuckle from strut or you can say vice versa I guess it's all up to you.
