Hi, I changed the tires of my 90' Camry with a hydro-jack. The part supported with the hydro-jack is the center of the suspension bar. I find it is the lowest part and appropriate with the jack-jaw. A question comes to me. What's usefulness of this part (like a half ball) under the center of the suspension bar? From the user manual I can see a hole at the lowest. Is it safe to use it to lift my car?
Thank you very much.
