Here's a old strip from 30th April 2001. This one's pretty autobiographical. We used to have a car which made a strange whirring sound somewhere near my footrest. I cured this by kicking the panel where the noise was coming from. It would fix it for a day or two but then the noise would return. Cue some more kicking from me. Noise went away. The car packed up not long after.
They should have a 'kicking' section in the Haynes Manual.
