The Owner's Manual of vehicles will point to spots where one can safely lift a car.
Yet the safe usage (not an option if one will be under the car) is to lift with a hydraulic floor jack and to use a jack stand. The base of the jack stand is quite large (as it needs to be).
How does one come up with two spots in the chassis (for each wheel), one for the hydraulic floor jack and another for the jack stand.
That's been a tough call for me for every vehicle lift. Once the vehicle is elevated, the jack stands can be slid under the vehicle, aiming for a portion of the suspension that does not compress when the vehicle is on the ground.
I've used leaf spring hanger brackets as a contact point for the jack stand, as the bracket is obviously mounted to the frame.
If the vehicle has a solid axle, there's an easy answer. I have a FWD vehicle without a solid axle and the pivot point for the suspension, which is located quite a bit inboard, will provide for a secure rest for the stand.
