"Thud" sound from rear....

Bump.
Have been troubleshooting this for a while now, and can't seem to find the problem....
Considering the rears are on the lower perch and the Tein springs are a shorter spring than OEM... does anyone think that the spring can be moving around when the rebound is happening, or does that just sound stupid?

How stiff do you have the Konis set? If they're soft enough, sharp bumps might be reloading everything too quickly.

Bear with me on this - I had the same issue on my ford focus after a Koni yellow rear install. The issue turned out to be the rubber insulator on the strut top mounting which needed replaced (the whole strut top mount).
Also, check the 2 bolts up top for the rear strut and the strut rod nut - I have heard impacting that nut on can cause issues. Hope this helps!

my guess is bottoming out - have you run a zip tie to indicate travel or alternatively looked at the springs to see if they're coilbinding? Moreover, running rebound higher than needed will result in packing down over a series of bumps leaving the vehicle essentially coilbound. Unless running some unGodly springrate, may want to back off per the KONI recommended adjustment procedures. Don't suspect TEIN's rate rates going much beyond midfirm if even that. Doubt it's the spring seating as that is typically a distinctly metalic sound.

Well, I turned all 4 struts down, about half way between soft and firm. Besides the car being softer, I noticed this 'thud' sound from the right rear, to be a tad bit louder. It could just be me thinking that though.
Also, it seems to be more of a solid faint 'knock'. I might take a look at the spring seat seals back there.

i installed konis and espelirs around the same time i swapped my cv axels. I get a weird popping thunk sound when the weight distribution of the car shifts. i think my issue is with the drive shaft though. I inspected everything and the were no rb marks and everything was tight
