When is a Car "Level" - Home Front End Alignment

Yeah I seem to recall that , an alignment shop will charge say $100 for a wheel alignment, but if they have to get into the caster/camber adjustment ,they want to charge more labor. Also keep in mind if the tech these days knows how to work with the cams properly, they strip and break if they are man handled. key is to take the weight off ,make the adjustment, then lower down and check. it can be time consuming for the wrong technician doing it if they don't have a clue.
