How does my local 4 wheel laser alignment specialist make the adjustment for the caster on my v220 i believe it has a mcphereson type strut,as they seem to leave that measurement alone and only alter toe and camber.Toe and camber are in green so i presume ok ,but they still leave my caster setting with left side green ie ok but right side in red.Im going to put it in again but would like to know if it is possible for me to tell if or what bolts have been adjusted . No wear on suspension or steering parts have been found ,steering still little resistence turning left and steering wheel slow to return to centre.Right hand turn ok and steering wheel centres.
