Do some research on bumpsteer and drop pitman arms. I thought it was common knowledge that the drop pitman arms supplied in some lifts are worthless.
I'm sure others have explained it a whole lot better than I can. As the axle moves up and down it follows the arc set by the trackbar. The drag link needs to follow this same arc as closely as possible. If it doesn't, unwanted knuckle movement or steering wheel movement will result as the suspension cycles.
