I too had to get the left and right ball joints changed out.
It was making a creeking / rusted part sound when turning the steering wheel left or right.
Lucky i was able to drive to repair show today to get it fix. It started happening to the car couple of days ago. And the noise got obvious by yesterday.
I have 135K mi. on the car now. Its 1999 GS400. It is lowered also.
Thanks to this thread, alot of people can read about this and really know and be prepare for it when it happens to their car.
Again, great post for those who own one of these cars.
