Kym on occasions and at the beginning of real 4wd tracks, was out of his vehicle and observed tinkering with his front knobs (actually his locking front wheel hubs), as you do with standard model 80 Landcruisers. Nobody ever slowed down to wait, his fellow passengers heard him muttering. (Craig actually made a comment to Kym that in ancient times one would perform this fine but lost art to 4Wdriving).
