- A missing cotter pin on a castle nut connecting the drag link to the pitman arm.Cevap
- CPower steering fluid level resting midway between the 'Add' and 'Full' marks on the dipstick.
- DPower steering pump belt deflection of one-quarter inch when pressed at the center of the belt span.
Cevap
A missing cotter pin on a castle nut connecting the drag link to the pitman arm is an unacceptable defect that requires immediate correction.
Steering linkage components—including the pitman arm, drag link, steering knuckles, and tie rod—must be structurally sound and securely fastened. Castle nuts must be tight and locked with cotter pins. A missing cotter pin allows the nut to vibrate loose, creating an immediate danger of steering detachment and vehicle control loss.
