Problems with rear axle behaviour, 1750 GTV -71

[Antti Sukuvaara <antti.sukuvaara@xxxxxxxxxx>]

I have restored 1750 GTV -71 which I got on the road first time at this
summer. The car has some odd behaviour at bumps and also during
acceleration. I haven't been able to find the reason. 

Symptoms are simple. Under heavy acceleration car likes to steer to left.
It seems so that rear axle turns slightly clockwise? I haven't found any
loose bushes anyhow, when I and my friend have together tried to find one.
Other symptom is that when the car takes off weight after the large bump at
higher speeds, it turns left again. And now dangerously! 

I have heard that this behaviour would be typical fault in 105 Alfas, so it
is probably known at the mailing list also. So for the safe and enjoyable
driving please help me. What are the reasons for that trouble? Bushes that
seem to be OK, but are not? Shock absorbers? Springs? Would you tell us how
you repaired your own 105 with the same symptom.

Thanks for any help!
