Time to put it to bed then...
The main gear are fitted with hydraulic shimmy dampers. They need to be bled every now and again. A give away is the crabbing and lots of shoulder wear on the main gear wheels. The thing is that when you bleed them you have to select the gear up and down to cycle the shuttle valve. This allows fluid to flow through the damper. Not popular for those with a weak heart.
I think.... it's been a while since I worked a real aeroplane. It's all button pushing and resets these days.
