Next time you have your caravan serviced ask to see the one shot nuts that are used to service your leisure vehicle.
And make sure the correct parts are fitted
See photo – The one shot nuts on the left are cheap copy’s ( One shot because they can only be used once )
On the right hand side are the correct type to be used with a alko chassic and will have ALKO stamped on them
Must be correct as these are torqued up to 280-290Nm of pressure and can cheap copys take this????
If not the whole wheel assembly could come off at anytime!!!
I ONLY USE GENUINE PARTS ON ALL MY WORK
