Well, I have only been able to do it to one strut so far, because I don't have access to deep enough sockets to get the other three. Most of the noise was coming from the front right strut. The nut on top was very loose, and the threaded part of the top of the strut had banged back and forth so much that the threads are completely smashed in. So I put three thick washers, enough to keep the nut above the damaged threads, and torqued down pretty hard......and.....no noise from that corner!! The other ones don't make much noise at all, but I will do the same to them when I get home this weekend and have access to deep enough sockets.
Also happy to be replacing my busted valve cover gasket and hopefully track down the cause of the puddle of water under my passenger seat that forms every time it rains (thinking sunroof drain?) this weekend.
Thanks 99prolx
