Vehicle Inspection第 11 / 120 题
You are checking steering-system play on a vehicle with a 20-inch steering wheel. How much free play is generally the maximum before the steering is considered defective?
a.About 4 inches
b.About 2 inches
c.About 6 inches
d.Any play at all is a defect
解析
Roughly 10 degrees of free play, which is about 2 inches on a 20-inch wheel, is the practical limit before steering becomes hard to control. Four to six inches is excessive and would be an out-of-service condition, while a small amount of play is normal in a mechanical steering system.
