pwede naman lift ang car sa sides.. may markers yan dyan kung saan yung lift points.. check your owner's manual nandyan lahat yan

regarding plug (pasak) thingy.. watch nyo sa youtube yung test na ginawa ni projectfarm kung ano yung effective na pasak product.. alam ko sa test nya may possibility pa din na sumingaw talaga yung pasak at pwede din mahugot ulit
I googled for about 2 hours reading about unibody and jack points, but it doesn't answer my question. I found the jack point in my Forester.



But a discussion I read mentioned:

Jacking Points on a Unibody Car | The Garage Journal

"As noted above, it completely depends on the make and model of car. The owner's manual will only talk about the jack points for the factory jack. The service manual will show you the jack points for a floor jack or lift. Many unibody cars CAN be lifted from the rockers. There are special pads that have a notch for the pinchweld, so the lifting load is spread out along the bottom of the rocker. Other cars have reinforced holes in the rockers for a jack. If you are using a floor jack, you can't go wrong if you lift at the hard points where the suspension arms attach to the tub. Some cars have reinforced subrails, or the attach points for the suspension cradles. Again, it depends."

This means yun pinch weld above is only designed for the screw jack in the trunk. It is not for general jack use. Note the pinch weld fits the factory screw jack head:



During the pasak, they used alligator jack on the pinch weld.



However ang tama is to use rubber support for the pinch weld like this:



Now my question is. For Subaru casa, how do they lift the Forester? By lifting via the pinch weld or are their other jack points written in the service manual and not shown in the owner manual? Remember the pinch weld is only designed for the car factory screw jack. In your car, how does the car lift support your car? via the pinch weld with maybe special pads?

Remember car tire shop is visited by all kinds of cars, so hindi nila memorize lahat na service jack points. This was why the pasak technician tried to lift by car via the suspensions. Should I ask Subaru casa where exactly are the service jack points, which I must convey to the tire shop? This is to ensure hindi ma damage yun pinch weld sa sides which is only very thin vertical metals (still puwede ma bend without pads).
