The panhard bar plays an important yet simple role: it keeps your axle centered underneath your vehicle, preventing it from shifting left and right. Setting up the panhard bar can be difficult. It is recommended you get your drag link mocked up first as there are limited options for setting up your steering, then you want to build your panhard bar to match the length and angle of the drag link as close as possible. Slight differences in length or angle could give you a bump steer issue. A steering stabilizer can help cover that up to an extent but the more severe of a difference between these two could lead to having a vehicle that is unfit for the road
