Difficulty: MediumSteering System Inspection

During a pre-trip walkaround inspection of a commercial vehicle, finding any missing, broken, or loose mounting bolts on the steering gear box is considered a critical safety defect that places the vehicle out of service.

Answer: Answer

Answer

True
Steering gear boxes must remain rigidly secured to the frame rail to ensure proper steering linkage movement. Missing, cracked, or loose mounting bolts undermine the integrity of the steering assembly and represent an immediate safety hazard that requires placing the vehicle out of service.

Step-by-Step Solution

1
Identify the component and defect condition described in the statement.
The inspection item is the steering gear box mounting hardware, specifically checking for missing, broken, or loose bolts.
Pre-trip inspection regulations establish strict criteria for structural and mechanical security of all primary steering components.
2
Evaluate the safety severity and regulatory classification of steering gear box mounting defects.
Loose or missing mounting bolts compromise the mounting foundation of the entire steering mechanism, creating an imminent failure risk.
Commercial motor vehicle safety standards mandate that all steering gear box mounting bolts must be present, undamaged, and securely tightened to prevent movement.
3
Determine the validity of the statement.
The statement correctly identifies the condition as a critical out-of-service safety defect.
The vehicle cannot be legally or safely operated until all steering gear box mounting fasteners are properly installed and torqued.
