Chucking?

What the cheapest way to prevent it?

We experienced sever chucking with our rig. I started by replacing the factory kingpin with an 5th Airborne kingpin. That helped but we still had some chucking going on. I then installed Air Bags in the truck with on board compressor so I can adjust the pressure on the fly. This all but eliminated the chucking. In retrospect, I wish I would have started with the air bags, then, if still required, replaced the kingpin. Good luck whichever route you take!
