i have a problem where front driver and passenger have .25 to .5 inch gap difference. eibach springs (used w 15k or so) were sat properly and bolts were torqued to spec while preloaded. yet im still having this issue.

i would like to know if you can preload the suspension while the car is on alignment machine and without taking off wheels. im assuming you can loosen the bolts from under the car and retighten them. plus preloading should be more accurate than jacking one side at a time. am i right or wrong?
