I frigged around for hours thinking i was doing something wrong with this same issue on Mr Hanky L series sedan and CA Wagon. On both i was using stanza LCA's in the end i used the sunny ball joints that give you more neg camber forgot part number and that helped a very little think its just the way they are man. With my next one was just going to slightly elongate the hole in LCA then mark and tack a decent flat washer either side to stop it sliding side to side.
