From looking at pictures online, the best and easiest solution will be to remove the wheel, brake rotor, move caliper out of the way, either drop the control from the frame, or pop the outter tie rod from the knuckle so you can swing the knuckle. Then knock the axle out of the hub. ( just like if you were doing an axle boot ). Then simply unbolt the wheelbearing hub assembly and it will probly come out w/ a simple tap of a hammer. The toyota prius if fwd right? The reason people use pullers is bc they do not remove the axle from the hub, thus the axle n hub r siezed together..( they are doing it the harder way) Someone correct me if I'm wrong. If you want, shoot me a PM and I can do it for you at a cheaper rate then the shop quoted you
