Clunking Noise After LCA Install

It can only be heard while driving at any speeds but there's no noise when rolling the body side to side or the trunk up and down. Any ideas?

Clunking or popping when car is in motion usually points to a bad pillowball of sorts. What suspension are you running, and is the top nut on the strut loose?

Running HKS Hipermax SP. I haven't had an issue with them at all. The top nut on the strut is not loose at all. I had double check everything made sure it was tight @ factory settings (for the rears) for the suspension. It's only the pillowballs of the lower control arms where it bolts into the chassis that is making the noise. As stated earlier, originally it was the passenger side with the noise, then I re-did them (no swapping of lca's as they were only off one at a time) and the noise went over to the driver side. Fixed it by loosening the nut that connected the lca to the chassis and the sound went away. After alignment, the driver side and passenger side came back (with the passenger side making noise once a while), and I had to re-loosen the nut again for the driver side to get rid of the sound.

Edit: Maybe @ISC Suspension can chime in.

Damn man, after about a week of driving around the passenger side started making noise again on my car. I jacked it up to see if I could find anything and one of the locking nuts was loose on the adjustment arm. I tightened it up and noise was gone. If you greased up the pillowball and everything is tight, maybe contact the vendor about getting a replacement?

The locking nuts are tight for sure. I double checked them, even after the alignment. I'm going to take it all apart one more time and then tighten the bolt connected to the pillowball and move it a lot to see if it still makes noise w/o having the strut/endlink connected to the LCA. If it does make noise/causes me to loosen the nut a lot, then I'll contact the manufacture instead.

OP, give us a call when you get a chance. We can try and figure out if it is a bad pillow ball or an installation error. Most of the time noise comes from the hardware not being tightened down enough. What torque specs did you use for all the hardware? Sorry for not replying earlier, did not see this until today!

It's okay. I will give you guys a call asap but for sure by today. The torque spec for each bolt from inside out was as followed, lca to chassis @ 59 ft/lbs, endlink @ 29 ft/lbs, coilover @ 59ft/lbs, and hub @ 59 ft/lbs. This was done while the car was still in the air as well as when it is on the ground.

I actually got it fixed. The supplied tube of lube wasn't enough for the pillow ball joints I guess. Bought some automotive grease and just put a lot of it in the joints. No sound as of right now.

Glad to see you got it resolved. Let us know if there are any other issues!
