this is probably different but i figured i'd post it here for reference...
i used to get a popping / clunking noise from the front suspension (i have TEIN HE's) when going out of my driveway or over small bumps...
i happened to be with Dousan at the time so i asked him about it..he said he had had the same problem and it drove him crazy until he tightened the nutt which the shock dampener adjustment pin sits inside of in the top of the strut...i wish i had a picture but those with Teins i'm sure know what i am talking about (the nutt in the middle of the pillow ball mounts)...anyway after tightening this nutt the noise was eliminated...
to tighten the nutt you need to hold the coilover assembly still with either the enclosed wrench or your friend's bare hands while you tighten the nutt on top...
anyway like i said your problems sound more involved then this but ya never know..
good luck..
