Thanks for your thoughts guys. The way ahead is no doubt to get a socket and torque wrench man enough for the job. Currently I don't have either, so I have added them to the long list of stuff I want to pick up when time and finances permit. In the meantime I've added some discrete marks to the nuts and wheel which I will check as part of walk-round inspection I undertake before each journey.
Kind regards to all
