.... it.... pitched up and down.......
As greendemon suggested, ball should be clean, and above all dry if you have Alko stabiliser coupling head, otherwise greased.
Pitching probably caused by 'noseweight' being too low. Noseweight should be between 4% and 7% of the weight of your van, but not exceeding 'max drawbar loading' figure for your vehicle.
