2004 Touareg V8 Alignment

Year
The car does not drive very well. Once I letgo of the wheel the car immediately steers to the right and I have to bring it back. The front left tire is not that smooth when in high speed especially hitting the 70 mph.
I am looking at crissing the front two tires with each other and see what happens. So far I have had 4 alignments and going for 5th one.

Yes my car has been on those kind of machines every time I go for realignment and it’s the same thing. I will keep going to the shop for realignment if it’s not right because I have 6 months alignment warranty.

I did some research and I feel like it’s may be my ball joints on front left side. Based on what I read about ball joints and symptoms, I can definitely relate that to my car. First I thought it was the front left tire. Then i took it to the shop and switched the front two tires with each other and also did wheel balance on all of the tires and still the car pulls to the right, which means the tires are good and they have lots of thread left. Now I suspect it’s my ball joints. Could it be?
