Control arm camber bolt washer play Help Plz.

If I remember the cam bolts are 1/2 " with fine thread nuts. I greased them as well, said in above post, easier to turn them. I have my own turn plates and long acre alignment tool. The cam bolts moved on me too. I thought I had them tight enough. I did not. So I re did my alignment and torqued the cam bolts 85 foot pounds. They haven't moved in six months. I marked them for quick visual inspection.
