my experience is that they dont woek their way out if the LCA. that being said, the do move in and out a little, causing some really odd problems.
i pulled mine after about 15k, and the inner pivot literally fell out. used energy suspension.
after switching to rubber, most of ny handling issues were resolved until i blew the car apart dor a full resto.
an added benifit is a slightly stiffer efective t bar rate.
