Wheel alignment explained & animation: camber, caster toe | toe in toe out explained

wheel alignment wheel alignment is basically to measure and  adjust several complex suspension angles   including camber caster and toe angle wheel a line that ensures that the wheels  are pointing in the right direction   what is camber camber is a measure of the  tire's centerline relative to the road surface   it is measured in degrees and has  a great influence on the driving   dynamics of the car negative camber  the top of the tire tucks inwards positive camber the base of the tire tucks inwards positive camber combined with steering  axis inclination could be adopted   to reduce steering effort and minimize  tire wear what is steering axis inclination   the steering axis inclination is the angle  between the centerline of the steering axis   and the vertical line from the tire  contact surface in a front view   the distance between the steering axis and the  center of the contact batch is the scrub radius by combining the steering axis  inclination and positive camber   the tire has a smaller scrub radius thus  has less steering effort and tire wear for street driven vehicles it is typical  to maintain a small negative camber   for racing cars an increase in negative  camber is adopted to improve cornering negative camber improves handling by keeping  better contact of the tire with road while the   car rolls as the car rolls it puts most of the  weight on the outer tire therefore it's better   to have negative camber on the outer tire to  ensure the tire's contact patch is evenly loaded the downside of negative camber is it will reduce  the peak tire grip during straight-line driving different suspension designs will  have different camber gain curves   for example a mcpherson strut suspension has  small camber changes with body roll because the   strut is moving linearly the wheel gains camber  to a certain extent and after that will start to   lose camber this could hamper a car's handling  and experience a lot of body roll and cornering a double wishbone setup can generate significantly  more camber gain by shortening the upper control   arm this is beneficial when the car goes around  the corner due to the shorter upper control arms   the car will have slight negative camber on  the outside so the outer tire goes flat with   the road surface this is where the car wants  to maintain the maximum amount of contact   the inner tire will have a slight positive  camber it is pressing flat against the road what is caster caster is the angular displacement  of the steering axis from the vertical axis of the   wheel viewed from the side positive caster is when  the wheel is in front of the upper pivot point   negative caster does the opposite modern vehicles use positive caster  which generates an aligned torque   to help straighten the steering  wheel when the car goes forward an example of positive caster is  the front wheels of a shopping cart   the tire patches behind the steering axis  as you push the cart in any direction   the wheel always follows  the direction you are going what is doe toe is the direction the tires are  pointed relative to the vehicle center line   viewed from above go in tires point  inward the angle is positive go out   tires point outward the angle is negative toe  angle helps the tires run parallel to each other towing is typically applied in a rear-wheel drive  car a rear-wheel drive car pushes the front tires   this causes the tires to push back  with respect to the suspension   therefore rear-wheel drive vehicles use towing  adjustments to compensate for this movement   a front-wheel drive car does the opposite the  front tire pulls the car the weight of the car   body resists forward movement this pulls the front  wheels forward with respect to the suspension   therefore front-wheel drive vehicles use  toe-out adjustments to compensate for movement   the toe angle improves steering response towing  reduces oversteer and toe out reduces understeer however excessive toe settings  can cause steering to be unstable   it also leads to excessive tire wear you
