  1. Approximately 2 inches (about 10 degrees)Cevap
  2. B
    Approximately 4 inches (about 20 degrees)
  3. C
    Approximately 6 inches (about 30 degrees)
  4. D
    Zero movement, as no free play is legally permitted on power steering systems

Cevap

Approximately 2 inches (about 10 degrees)
According to official CDL inspection guidelines, steering wheel play should not exceed 10 degrees, which equals roughly 2 inches on a standard 20-inch steering wheel. Any play exceeding this amount indicates potential mechanical defects or loose linkage.

Adım Adım Çözüm

1
Identify the standard steering wheel diameter and power steering system check criteria
The vehicle uses a 20-inch diameter steering wheel with power steering.
Free play thresholds are calculated based on angular degrees translated into rim circumference distance.
2
Apply the commercial vehicle inspection standard for maximum free play
The maximum acceptable play is 10 degrees, equal to roughly 2 inches on a 20-inch wheel.
Excessive free play beyond this threshold can delay steering response and make handling hazardous.
