In one of the earlier posts someone was mentioning difficulties in undoing wheel nuts because they were too tight.
If you have a look in your maintenance handbook, it should give you the torque tension for your wheel nuts, i.e. Nissan Navara D40 - 83ft/lb. We deal with a Tyrepower dealer who torques most cars between 80-85ft/lb, caravans and trailers would be the same. For the cost of a torque wrench and socket, it's money well spent and you can also request that they do not use a rattle gun on your car.
