That's what I'm getting, with rears you have to take it all off then best to put in new bearings so bang them in, I had one on and back on in about 20 mins, jacked up already though. But need that tool to wind back the piston back! Fronts I rekon would take a matter of minutes. That's my first time doing it aswell. Something that simple you might as well take it to a normal garage.
