Touch the other 3 units which still work? You must be kidding.
And the solution would be typical: add a few kilograms of weight
to the car (tire +glue), make that wheel wobbly (the glue won't
be spread evenly and who would care about balancing a fix like this)
so the ride will be bumpy, never mind the vibrations
might pull the whole thing apart and kill someone - "on very rare
occasions".... :).
