All of the following statements are true EXCEPT:
A) wheels with equal caster will cancel each other out, and the vehicle will steer straight.
B) too much positive caster can cause front-wheel shimmy.
C) negative caster aligns the steering axis with bumps encountered in the road, so road shock is more likely to be felt through the steering wheel.
D) too much positive caster can cause cupped tire wear if the resulting shimmy is allowed to continue.

Question

Quizplus · Accepted Answer

Negative caster actually tilts the steering axis rearward (not aligning it with road bumps), which can reduce steering effort but also decrease straight-line stability. Positive caster, on the other hand, aligns the steering axis in such a way that it improves straight-line stability and can indeed cause the effects mentioned in options B and D.
