Hello all, I'm hoping that someone can advise me.
I have a stock standard AU series2 SR sedan. I've had it since new. I have
noticed that every time I have say 3 people in the back, or towing a
trailer, or having a heavy weight in the boot, I can feel a high frequency
vibration. The vibration can be felt in all seating positions and is most
noticable at speeds of around 45 to 55 km/h. Although I can still feel it a
bit at high speeds. It has been like this since new.
The problem was reported to my dealer/service manager and he had the
tailshaft replaced (warranty), saying that it was out-of-balance. However,
the problem still remains.
They now tell me that they cannot reproduce the fault and seem to be
avoiding my concerns by fobbing me off.
I am a mechanic from way-back and I suspect a tailshaft alignment problem.
It can only be felt when the rear end is lower to the ground.
Is there anyone else had or heard of this vibration problem?
I am particularly interested in finding a possible fix. I was thinking of
altering the mounting height of the gearbox??
I am open to suggestions....
Any help would be much appreciated.
