Where Is the Drag Link on a Semi Truck?

The drag link is an important part of the steering system on a semi truck. It is connected to the pitman arm and to the steering knuckle, allowing for the transfer of force from the steering wheel to the wheels of the truck.

Without it, a truck driver would have difficulty controlling their vehicle. To find where this drag link is on a semi truck, one must first locate the pitman arm.

The pitman arm is located on the steering box. It is connected to the center link and then to the idler arm.

The idler arm helps support and balance out the steering force from the steering wheel while also keeping it in proper alignment with the rest of the suspension components. The drag link connects to both ends of these two components and runs along with them.

The drag link should be easy to identify as it will have a ball joint or u-joint at each end, which allows for flexibility in movement and reduces vibration from bumps in the road. It will also be slightly thicker than other components of the steering system due to its heavy duty construction.

Once you have located where your drag link is on your semi truck, it’s important that you inspect it regularly for signs of wear or damage. If your drag link becomes damaged or worn out, it can lead to poor handling performance and cause safety issues while driving.

Conclusion: The drag link on a semi truck can be found by locating its connection points – namely, at either end of both the pitman arm and idler arm – which are both connected to either side of its center link. Inspecting this component regularly for signs of wear or damage should be done as part of any routine maintenance schedule as failure to do so can cause poor handling performance and potential safety issues while driving.
