Coincidently I have just mentioned a bit about tread runner removal on another thread. I had my car wings removed, (a roadster) a few years back for respray. The workshop had to remove the tread runners and despite the car at only 3 years old at this stage, the screw shafts on the tread runners were all rusted beyond hope. All of the tread runners had to be replaced. It seems, as has already been pointed out, "they all do that sir"
