So I just got done with a grueling spring/camber kit install (rear only on camber/toe kit), and I just took it out for a spin. And.....my heart sank because the front end just creaks and grinds and feels unstable. I double checked all of the bolts/nuts, and they are tight, except for the center strut rod, when I put the nut on it just keeps spinning and never tightens. With that said, I checked the nut/threads and they are not moving. The rear of the car feels solid, is there something I can check without having to remove the damn strut assembly, because honestly I could do that and put it up there again and still have the same problem.

Any ideas???
