For a start 'supradupe' ...I'm not trying to explain this to you .
For another, I am telling 'sunedog' what has happened with noises like this before...'workshop pattern failures'...now, if you have practical input, let's hear it...if not, your not being helpful.
There have been problems like this with shocks not having the upper bushes under enough compression when assembled and the 'thump' is from the wheel dropping into the dip and pulling on the upper mount bushes, the return stroke is what causes the noise, as the lower top bush now has a little room to move upward to cause the noise. A thicker bush or shortened spacer will compress the bushes more to not allow unloading of either bush........this movement of the shock is due to the compression stroke being heavily damped as opposed to the relative soft stroke of the shock extension.
The upper spring mount on VW front shocks causes a similar problem due to end float in the bearing assembly.....the cure is to remove the spacer and shorten it slightly untill the noise goes away.
An what's more 'supradupe'......I fail to see the reasoning in your post .
