John, that's some great advice, I guess I should switch to illogical thinking, but the noise is just too mechanical and always the same.

I have been driving like this for half a year and as much as I tried to change the variables that I assumed would come into play, nothing made a difference, so you could be right in a way, but I serioulsy doubt it would be related to wind or road surface.

I was thinking about driving without the rear calipers on, just attach them to a spring so they don't bounce around, but to be honest, I'm a bit scared to do that and reach a speed where the thump is most noticable.

Right now I got the e-brake shoes and lines off on the rear, so if I did that, it would leave very little to even look at for problems.

As for where it comes form, I'm quite sure it's the rear since my engines makes a whiney noise and it is clearly heard from the front. I do agree that noise travels in a car, which is probably the reason I have not solved this yet.

Tomorrow I will be doing the second bushing on the spring link, I will see if that yields anything, those had to be changed anyway. Perhaps wear in some part cause the suspension or somethings else to move to a position that would cause something like this to happen.
