I checked my tyre pressures, wheel torques and hubcentric rings and all seemed ok. So then I had the wheel balance checked and voila!

front wheels 35g and 45g out.

rear wheel 175g out..............ye gods!!! Other rear 60g out.

Got all rebalanced properly and she is as smooth as silk again.

VERDICT: The new bushes were mounting the rear subframe far more securely allowing the severely unbalanced rear wheel to transmit shake through the car.

Overall, the car now steers and handles better and is much quieter. I am very pleased.
