Could be several possible causes. 1. worn out torsion bar 2. bar was installed (clocked) wrong. 3. Socket in the crossmember has spun due to rusted out crossmember.
I would check the crossmember first.

Yep. Looks like whoever installed the torsion bars had the LCA not hanging all the way down so the bars aren’t able to lift the car.

Or the bars could be weak, or the wrong bar.
