Be careful using the jackstands on the control arms, parallel link/radius rod area of suspension. These parts typically cannot sustain the weight of the car, and service manuals will specify not to jack up the car or support it at these points.
Now, if there is a welded bracket to the chassis that the rear radius rod goes into, that's another story, as that is the jackstand point on my car. You just don't want it really on the arms. And be careful for example on the front transverse link bushing brackets for example - if you set your jackstand on those big M14 bolt heads, it could stress the weld anchor in the chassis and potentially break it or weaken it.
The service manual will usually have jackstand points to support the car, and well as lift points. I personally beleive that supporting it on those body weld parts are BAD as [censored], if I look at my maxima, the rust that appears is mainly in the area where the garage sets the 2 pole lift arms into the car.
The garage will usually use these points on all cars. I suspect the crunching on that specific spots creates stress cracks and over time salt and rust developed in those stressed areas. Just a hypothesis.
