There's the two bolts that hold the strut to the knuckle. The bottom one is round; the top one is an oval allowing camber adjustment. That's the one that "slips." If it slips again, I'll pick up a set of the bolts. I'm hoping the cam-bolt will set the camber, and then not let it slip. The guys really torqued them down this time, so hopefully it won't slip again.
