4. Caster action on the front wheels of a vehicle will
a) make it easier for the driver to take corners
b) help reduce the load on the king-pins
c) automatically achieve the straight wheel position
d) none of the mentioned
View Answer

Answer: c
Explanation: Negative caster produces directional stability to the vehicle keeping the wheel position straight.

5. Too much toe-in will be noticed by
a) excessive tyre wear because of taking corners
b) steering wander
