SO I just replaced the front left lower ball joint and the cranky bed spring sound is still there. I think it might be my shocks or shock absorbers, which will soon be replaced by KW variant-1's. Is there any other suspension parts that come to mind that would make that kind of noise? i have a pair of extra sway bar links for my hotchkis set-up. I guess I'll just start replacing everything

 

How many miles on your Z and year? Also, if the sound is loud in the car maybe post a video?

 

My Z is a 2004 with 86k

 

Im installing some KW variant-1s tommorow and changing out the sway bar links...This sound better f****** stop...I want my equips to come home to a happy car...

 

Before I got the wife her FRS, she had a Chevy Sonic LTZ. For a time, it sounded like the front end was going to literally fall the **** off or something. Probably the worst clunking noise ever. I checked everything, motor/trans mounts etc. Like a dummy, the only thing I didn't check were the sway bar end links. I poked around online and found out there was a recall on faulty end links. Brought her in and sound was gone after that.

Anyway..... I hope everything works out for you and that sound goes the hell away.

 

Nice screen name. jk.

 

So I noticed this noise after the jack slipped an inch and the left side of the car I have replaced the front left ball joint and the rear sway bar links and the sound is still there...This is a dull bed spring sound when going slow over uneven roads especially entering parking lots...wtf is wrong with my car!
