I know this thread is a little old but I just came across this same problem, tires were wearing terribly on insides up front and just did control arms and had it aligned and put new tires on, still wearing funny. So anyways, what I did was take the nut that sits right on top of the strut mount off, and then when you tighten the top one it sits down into that hole nicely. Either way this seems like a crappy design but I don't see why this wouldn't be the best solution. Does anybody have any reason why this is not a good idea? Any input would be highly appreciated!
