The apparatus and method is utilized in a drive-through vehicle washing system of the type in which a vehicle is moved by conveyor along a longitudinal path across a floor surface, past a series of washing stations. The apparatus attaches to a parallelogram linkage such as that of a tire washing station and includes a manifold for spraying pressurized liquid at the vehicle wheels from an outlet nozzle. The manifold is carried by a drive mechanism which translates the manifold longitudinally to follow the vehicle wheel passing thereby for a distance sufficient for the stream of liquid to claims the entire wheel circumference. A flow control valve for regulating the flow of liquid is provided along with a sensor for detecting wheel position. A control mechanism regulates the movement of the manifold and the flow of pressurized liquid causing the manifold to move at a speed substantially equal to that of the vehicle. The method of operation in a specific linear actuator for translating the manifold is also disclosed.
