I would love to take one of those urethane bushings and put it under 500 lbs. of load to see how much it deforms. Urethane can be stiff, so it may be creating that much force. What is the distance from the hitch ball to your front wheels? I want to run some numbers now that I have weights to work with.
Thanks for posting all this stuff!
