do you have any knowledge or have worked on a car? if so, start removing bits to find the root cause. here's where i would start on rattles.

listen for which part of the car the noise is coming from. Is it the front or rear?

unlink one of the endlink (dont need to remove) front or rear and see if that eliminates the noise.

if not, link the endlink, remove the strut or shock and replace using stock bits. dont worry about the alignment for now.

if you determine it's the shock or strut, use the stock mounts on the aftermarket strut/shock and see if the noise comes back.

if it doesn't then it's your mounts.

if it does, then it's your stock/strut. get it replaced.

finished.

its most certainly the right rear.i guess i will try that trial and error approach. Unfortunately, thats going to take me such a long time to do in my garage. i have some knowledge and have worked onmy car before, and i mostly learn by doing and reading , and i've never DONE suspension so i guess it will be a learning experience.

my mental issue right now is, if it was something install related, i can see no reason why the install shop would spend an hour checking everything and NOT fix it. furthermore, if it were install related, it would have presented itself immediately, or very soon after, not after 2 weeks.

I couldn't hear any noise in the sound clip. Is it a clunk sound or a rattle?

its more of a rattle at this poinnt. turn your speakers up a bit and you will hear it. its throughout the whole thing. it might be hard to hear because it barely stops. its like bummmm bad dum bumm. i have sound clips that are better as well, but not on youtube.

If it's a constant rattle then I don't think it's The spring mount. You should have someone bounce inside your hatch and look underneath your z.

i have bounced in the hatch, and the noise happens. i'm gonna take the wheel off and see if i can't find any issues right now.

i wouldn't count on it just being an installation issue. it can well be a manufacturing defect. if it's not the endlinks i would check the rear spring orientation (some springs rub against the carrier unless positioned a certain way), pillow mounts could make noise too if worn, but it's too new so i would consider it a defect if it turns out the noise goes away when you use stock mounts.
