Lowering springs issue - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I installed some used 1" lowering springs all around. I now hear a rattle/clunk every now and then coming from mainly the fromt right side strut. It almost sounds like something is loose. What are some troubleshooting tips to look into?

If the spring is seated correctly (there is an obvious "seat" for the bottom of the spring) then likely something is just loose - even the threads I've read where so-and-so double or even triple checked every nut and bolt, they and up finding a loose one, so all I can say is check every nut and bolt again.

Recheck all bolts and also recheck your torque spec info. Helped a friend with lowering springs and on the test dive we heard a knock as you described while under power and cornering. We went back to the shop and to recheck our work to find that we had used too low of a torque on one of the bolts. It’s easy to get confused with the various joints and knuckles having different specs.

Only thing I haven't checked on torque specs again is the sway bar end links. Will be doing that today and then report, thanks

update : swaybar endlink was loose. all good now

Bottom swaybar endlink was loose. Tightened a bit and the clunking/rattling sound disappeared, however I still hear a Pop when I turn hard left or go over speed bumps. Has to be the strut mount because I've checked everything else
