Yes, it is possible to replace shocks or springs individually.

You should compare the cost of replacing the complete assemblies yourself to the cost of replacing individual components with the assistance of a shop.

Use a floor jack placed under the differential.

Clean the lower end of the steering knuckle and have an assistant grasp the lower edge of the tire, moving the wheel in-and-out while you look for any movement at the steering knuckle-to-control arm balljoint. If there is any movement, the suspension balljoint(s) must be replaced.

If leakage is noted, replace the shocks as a set. However, a light film of fluid is no cause for concern.

You should first loosen the front wheel lug nuts, then raise the front of the vehicle and support it securely on jackstands. After applying the parking brake, remove the wheels. To remove the upper shock mounting nut, use an open-end wrench to hold the shock from turning while removing the nut.

Raise the rear of the vehicle and support it securely on jackstands.

The specific components discussed include the rear hub/bearing assemblies, driveaxles, and shock/spring assemblies.
