Groaning Troll 550 GT 2004
Having sorted most of our problems out, our Troll 550GT 2004 still groans. Any suggestions please?

As above.

Try rubbing the towball with fine emery paper or wet and dry to remove rust, paint, dirt etc then do the same to de-glaze the pads in the stabiliser.

Then, and this is important, clean the towball and pads with a cloth soaked in brake cleaner, alcohol or meths. You will be surprised how much muck ends up on the cloth.

Chances are, this will cure the problem.

Can you hear the groaning all the time or only when travelling on roads at slower speeds?

Our always groans when towing around towns, over speed bumps etc but we don't hear it on fast roads.

But have you been cleaning all the muck off with a suitable solvent after de-rusting and de-glazing? (You don't mention it)

It really is essential.

I had the groan this year on the final leg of my France trip. The ball looked nice and clean so I did not wipe as usual with the brake cleaner spray I carry. An obvious mistake.
Strange thing is the 3 x Alko hitches I have had on my vans have always groaned to some extent, but I do not remember this being the case with the Winterhoff I had on my 2006 Familia. This definetly felt to the hand a far nicer and more substantial piece of kit.
