Nuts are tighten up to a couple of grunts and a big heave. It was the old story of getting the grub screw aligned......after it's service one wheel was not 100% and while I checked they were tight before setting off, I did this cold and as a result when hot one started to come loose. We had done the A93 and some 90 miles of pretty hard driving that morning, let alone the 350 miles of motorway thrash to get there.
