Never change a single shock absorber. They should at least be changed in pairs (both front or both rear). If replacing OEM shock absorbers, then changing all four is recommended. If one is bad, the others aren't far behind.
Understand that testing shock absorbers is very important. Surveys clearly indicate that most drivers don't realize that shock absorber condition is critical to vehicle safety. Providing a comfortable and pleasant riding experience is actually a by-product of shock absorber function, not the object. Vehicle control and reducing wear on the rest of the suspension are the primary jobs of shock absorbers. Comfort and handling come from the overall design of the vehicle and its entire suspension system.
