I was ever-so-slightly embaressed and a more than a little bit glad that they'd retested it rather than just going 'oh yes, new disk, that'll do'.

As I understand it this is usually the case, but a colleague at work who used to drive a Minor told me he had one collapse on his Minor as he went over a hump back railway bridge in Ashford doing about 40mph!Don't worry - the king pin swivels can only fall out when the wheel is lightly loaded - often when turning in at low speed.
at which point I expec the wheel is completely unloaded (until it lands with a heavy thump - or in his case as smash, clatter and a deep plough line in the tarmac!!)as he went over a hump back railway bridge in Ashford doing about 40mph!
