Answer 1- No straight line stability, tyres will vowel, Negative caster was seen on ancient cars but today\'s car have only positive caster.

Answer 2- Positive caster will increase steering effort, create disturbing effect to driver because it will try to maintain straight line stability so create resistance due to mechanical trail. And driver will not get any warning about lose grip of wheel.

Answer 3- It will amplify torque steer so it must be kept minimum.

Answer 4 - In reverse Ackerman, outer wheel steer more than inner wheel, percentage value will be negative.

Answer 5 - (2700/4000)×100 = 67.5%

Answer 6- In MacPherson strut geometry, revoknuckle will reduce spindle length so ultimately torque steer will be reduced.

Answer 7 - Two tierod errors are due to wrong Length and angle of tierod .

If length is high then during jounce and rebound it will have toe in and if length is small it will have toe out.

If angle of tierod is wrong then during jounce it will be toe out and toe in during rebound
