I have a 2002 Ford Focus ZX5 that has a rattle/vibration. I have been
trying to get the dealership to diagnose this for eight months now.
The noise started two weeks into me buying the car used with 21,000
miles on it.
The noise is a metallic rattle coming from the driver's side. It
happens in any gear between 1900 and 2100 rpm. It doesn't happen
during idle. If you rest your foot on the clutch the noise disappears
(not depressing it, just resting). It is especially loud when under
load (driving up a hill).
The dealership has checked out the heat shield, replaced the
transmission and clutch kit. Now, they are saying that it might just
be "normal" for this vehicle (which I am not going to accept).
