- Drag link is a long bar that provides a connection between the tie rods to form
one big moveable linkage system. It’s called a drag link because it “drags” the
whole steering linkage from right to left. - The idler arm provides support for the linkage system by connecting to the
drag link and the vehicle’s frame. The pitman arm is connected to the drag
link and the steering box. The pitman arm commands right and left movement
of the linkage system, causing the vehicle to turn right or left. - The steering box converts the turning motion of the steering wheel into right
and left movement of the steering linkage. This is achieved through an
internal gearing system specifically designed to convert circular motion to
right and left motion. Sometimes referred to as the “steering gear,” the
steering box is mounted to the vehicle’s frame just above the pitman arm.
Rack and Pinion Steering System Components
- Steering rack and tie rods: The rack contains special gearing to convert the
turning motion of the steering wheel to right and left. This design eliminates
the need for the steering box, threaded adjustment sleeves, drag link, pitman
arm, and idler arms.
So how do we keep our tires from wearing out as they roll down the road?
Regardless of what types of suspension and steering system in your car, with all
the parts that make them up and all the movement going on, there is going to be
wear and tear, and parts will simply wear out. Worn out parts cause
misalignment of wheels, and this results in tire wear.
