Suspension thump noise?

hey im pretty new to this website but figured id get some advice

just installed a eibach stage 2 with a set of jba upper arms, shortly after the install i ofc i got an alignment. was fine for couple hours of driving felt great but eventually i got a thump whenever i would go over anything. i cant figure it out does anyone have an idea what it could be? i would greatly appreciate it

here is a video

You check whatever nuts and bolts are all tight? Not loose?

 

yeah everything was torqued to the recommendation when i did the job, cant seem to figure it out

 

If you didn’t do a sway bar drop, is the sway bar hitting the spring.

Saw what you just posted so taking out my other questions.

I was going to ask if the UCA is hitting the tire but that sounds like metal to metal.

 

Are there any witness marks on your coils?

 

so when i bought my suspension i also bought a drop for the sway bar aswell. but do you possibly think that threw off the sway bar link in anyway bc i really cant think of any other possibilities

 

no my coils and uca clear everything perfectly

 

Shouldn’t… at least not that I remember reading here anywhere


are the lca bolts to the frame tight? Sometimes the alignment shops don’t tighten and torque them.
