As the title says, it's pretty straightforward. Installed some coilovers in the front end of my 06 today, and they ride smooth in a straight line, but while turning there's a rumble and some shaking. Could this be due to the little (maybe 12mm?) hex bolt that's above the 2 giant bolts that hold the strut to the hub? I didn't adjust it at all, got fed up after fighting a sheared off end link and dropped the car back down. Everything else is tight as it should be.
