My 2001 AU2 SR sedan is now approaching 100,000kms. (had it since new).
Although it's been a pretty good car thus far, I'm still being annoyed by
high frequency vibrations at slow speeds (40-50km/h) and a droning/cyclic
humming at cruising speeds (100km/h). This extremely irritating phenomenon
occurs when there are at least two passengers in the back and it seems to be
worse when there is extra weight (luggage) in the boot. I have not been able
to find a cause nor cure for it after many discussions with my local dealer,
mechanics and various internet forums.
So far, in attempts to fix it, the tailshaft has been replaced, the
front-end checked and all found to be within spec, the shockers inspected
and new tyres fitted all 'round. No difference. I'm now wondering if the
exhaust system has something to do with it?? Is this possible? I ask this
question because I was thinking of fitting a performance exhaust system to
it, but I am concerned that the 'droning' noise will be exacerbated.
Anyway, at the end of this year I will have to decide whether to keep it or
sell it. The main reason for selling it will be because of the problems
mentioned above. After all, it has been a good car to me in all other
respects.
This post is essentially One last effort to obtain a satisfactory remedy to
this problem. If I can fix it for sure I may just hang on to the car for a
few more years.
Has anyone else experienced this with their Falcon? If so, how did you fix
it?
Any suggestions most welcome.
