control arm help

right now i have djm adjustable control arms on my bagged 2000 silverado i have had nothing but problems they keep comin loose and it just freely moves while drivin one side will have good camber and the other will be way off is the anything i can do to fix this if not what type of control arms should i get any help would be appricated

I dont think I have ever seen an adjustable DJM arm before

yeah ive looked on line cant realy find any thing on them mabe im wrong about them theres a bolt on the upper arm turn one way or the other sets the camber positive or negative not to about realy

probably chassis tech I remember seeing designs like that before. But If you are interested in DJM arms I do sell them.
