Wheel balancing didn't help, the wheels weren't bent (had them tested for trueness). I was convinced that it was therefore a drive shaft problem especially since it seemed to be more pronounced on left hand turns than right hand turns and at certain throttle openings. I was expecting to fork out largish $ for drive shaft surgery so I was pleasantly surprised when my mechanic told me it was just a loose pinch-bolt. Cheap fix for me - though your mileage may differ.
