Update: the right side is back together with the exception of the tie rods because I am waiting on the new rack. Before putting the calipers back on everything is tight and smooth. HOWEVER, as soon as I installed the calipers, the rattle is back when I spin the wheel back and worth. It sounds like maybe a piston is loose and rattling inside? Or possibly the pads sliding backs forth? Has anyone encountered something like that?
