Hate to dig up an old thread like this but I'm currently going through the same headache.
Got the same "woo-woo" noise when turning and vibration and low speed / lots of torque even when going straight.
- Replaced Both CV axles
- Replaced Motor Mounts
Cant be the brakes cause those have been changed out
Our mechanic has all but given up... but this car has plenty of life left in her.
I know the OP is long gone but does anybody suggestions?
Did the carrier bearings around the VCU help?
I'd take it to a dealer but the nearest one is 2000 miles and a long boat trip away!
