Quick question, reading about front link suspensions. Context: triangulated four-link using full hydraulic steering because using a steering box with a crossover draglink will cause bumpsteer. What the heck is bumpsteer?

quite simply if the track bar and drag link are not perfectly parallel and you hit a bump the steering wheel turns. When you do full hydraulic steering there is no drag link and therefore no bump steer. When going fast and hitting bumps the last thing you want is the steering wheel turning without you telling it to turn.
