During a comprehensive vehicle inspection, a commercial driver must inspect every mechanical linkage and auxiliary component of the steering assembly for distinct defect criteria. Match each steering system component on the left with its primary inspection check on the right.
- Steering column and intermediate shaftVerify secure cab/chassis mounting, absence of binding along the shaft, and no loose or worn universal joints.
- Power steering pump drive beltCheck for 1/2 to 3/4 inch deflection at the center of the span, ensuring no fraying, cracking, or glazing.
- Pitman arm and drag link connectionCheck that linkage arms are not cracked or bent, ball joints are tight, and castle nuts are locked with cotter pins.
- Tie rod assembly and cross tubeVerify the cross tube is straight, rod ends are secure with no excessive socket play, and clamp bolts are tight.
Cevap
Steering column and intermediate shaft matches with verifying secure mounting, no binding, and no loose U-joints; Power steering pump drive belt matches with checking 1/2 to 3/4 inch deflection and no fraying or cracks; Pitman arm and drag link connection matches with verifying linkage integrity, tight ball joints, and castle nuts locked with cotter pins; Tie rod assembly matches with verifying the cross tube is straight, rod ends are tight, and clamp bolts are secure.
Each commercial vehicle steering component has dedicated pre-trip inspection standards: the steering column must be solidly secured without binding or loose U-joints; the power steering belt must have proper tension (1/2 to 3/4 inch deflection) without cracks or fraying; the pitman arm and drag link connection must have undamaged linkage secured by castle nuts and cotter pins; and the tie rod must be straight with tight ends and clamp bolts.
