4 link suspension adjustments???

you can twist it 1/4 turn? or you can move it like up and down? is it sloppy? what kind of rod ends did he use? it doesn't sound like they are sealed. the best ones are Teflon, nylon or delrin sealed and wont let dirt or crud in. This is especially important on a street driven car. Did he adjust any of the lengths of the links or the bars? That can cause problems.
