[Whyman]

I have a Volvo/Thule/Brink which is probably the same as yours.

It has always had some play in it. I was concerned at first by this and first contacted Volvo who were less than helpful. I then contacted Thule who initially wanted to refer me back to Volvo but in the end agreed to have a look at it.

The conclusion was that whilst there was some play it was not excessive. I check it at the start of each year towing the caravan and as far as I can tell it has not got any worse. Having said that I do not tow anywhere near as much as you.

The guy did suggest that you might be able to buy a new socket the part the removable bit goes into and or the removable ball. I looked at this and it could probably be removed without taking the rear bumper off but did not follow up with Volvo.

If I had my time over again I would probably go for a fixed on next time.

Just a point your car cannot fail the MOT for the tow bar if the towbar is not fitted
