When adjusting a vehicle to counter the effect of road crown, what is the adjustment would you make-Adjust the left front wheel with slightly less positive caster-Adjust the right front wheel with slightly less positive caster-Adjust the right front wheel with slightly more positive camber-Adjust both front wheels with slight toe-out
Tech A says that negative caster provides directional stability. Tech B says that positive caster results from excessive positive camber. Who is correct
