I had this problem, I fitted two Heavy Duty Springs from Euro Car Parts -no more problem.

What is the height of your tow bar ball from the floor?
I have measured from the floor to the centre of the ball and it is 415mm.

According to this blurb its about right.....

What is the correct height for the coupling head on a trailer or caravan?
A height of 385mm to 455mm is stipulated by the EC Directive if the trailer or caravan is in laden condition. Laden condition refers to a trailer loaded to the maximum specified mass in this instance. The mass must also be distributed evenly over the loading area.
