The drivers side spring is not sitting correctly in the socket. The coils look like they are binding. Could be just old tired springs. The A-arm bushings could also be keeping the arms from extending down. Sway bars can also cause uneven arm height. You have to look at the top and bottom of the springs, they usually crack at the last two to three inches of the spring end. Check the front frame horns for signs of a previous accident. You really need a front end rebuild.
