THE COUPLING HEAD

If the tongue on the coupling head is loose, you may lose your trailer on the first bump in the road. Ensure that it’s in a good condition.

Check if the sock still connects.

Check the coupling head that secures the caravan to the tow bar.

Firstly,dome stillis thein one tongue piece? insideIf not,of the you’ll have to replace the entire head. The tongue is important, since it secures the dome to the ball of the tow bar. (It would be embarrassing to arrive in Margate only to realise your caravan’s still in Benoni. – Ed.)

The coupling has a draw bar and a shock absorber (also called a damper). If you depress the draw bar completely, the damper should push it back to its original position. If not, you should replace the shock.

Lubricate the draw bar (there’s usually two lubricating points).
