I installed the tein basics I had all new parts on for the bushings, upper mounts , even gaskets etc...Torqued to spec. when I drive really slow 5-20mph I hear this weird vibration loose spring kind of noise. I checked the rear springs and they are completely seated correctly in the seat. I thought it was alignment so I obviously got it aligned and the specs are perfect. I have kintex rear upper camber arms. Has anyone had this if so did you fix it? Any suggestions? This is for a G35 but since the suspension is exactly the same I thought maybe my Z fellow members can shed some insight on this.

 

Assume you done every thing right, just drive around, the sound will go away eventually. At least in my case it took almost a month.

edit: the noise occurs at a really very low speed 5-10 mph just like yours.

 

well its been over 3 months and its still there. It really sucks. I can't figure out if its just the speaker cover behind the rear window or something suspension related. It sounds like its coming from the top of the springmounts somewhere.

 

maybe is better to bring it to an auto/performance shop. check the center nuts of the strut as well as the 3 surrounding mounting nuts that they are secure.

 

ever think it might be swaybar end link probs??...sound almost like its clunking?

 

didn't think about the sway bars, I will check into it. The end links look fine. the sound comes at low speeds with straight driving. Would the sway bars make noise going straight?

 

striaght driving through bumps...but if the road is smooth...i have no idea

 

i have that noise as well but i am on cut springs...and i know one of my endlinks is loose due to me stripping the thread...but i do remember stumbling across a thread where they would hear a clunking noise and someone suggested it might be the endlinks...

sorry i am not of much help...but thought i would just share my experience
