('07 cobalt at present)
I've been putting cars up for 50 years, using various jacks and then blocking under the frame. I'm not bragging - some of that was wrong (blocking under the control arm) - but no disasters. I have never understood jack stands WRT (With Respect To) unibody cars.
I see what seem like two issues:
- Intuitively (to me), and per a lot of online advice, the stands should go on under the pinch weld. But, the geometry of the stand top seems totally wrong for this. The OE (Original Equipment) jack designed for that location is shaped to carefully cradle and support the flange. The jack stands I see would bear the weight on rocker panel and the floor pan. Jack stand pad that I see do the same. Further, the notch in those does not support the side of the pinch flange the way the OE jack does.
- If, instead, the jack stand is put under the engine cradle with just the front of the car elevated, ISTM (It Seems To Me) the stand would just make contact with the cradle along one edge, which seems unstable to me.
On the Cobalt, there is a cross-member at the front of the cradle. Do ppl put the stands there? They'd have to be considerably higher, and there are times when they'd be in the way.
Obviously, ppl (People) use jack stands. So, what am I missing?
