Suspension Noise- Can't figure it out
 

I have been having a rattling noise coming from around the passenger side front of my car for a while now, and I can't figure out what it is.

Symptoms: It sounds like something is loose or rattling whenever I go over bumps. It's most noticeable over smaller bumps, like driving over train tracks or pulling into a driveway. I don't really notice it over speed bumps. It's also far more pronounced when the bump is only on that side of the car (like driving over a manhole cover with that wheel).

I have already replaced all 4 struts, I have a new aftermarket swaybar set, and I have removed the undertray and it's none of those things. I did install some polyurethane compression rod bushings about a year and a half ago, and spraying WD-40 on them today didn't make the sound go away either. I also had the passenger side wheel bearing replaced and I doubt they would have reconnected all that stuff if something there was loose.

I don't know for certain, but I also want to say that I think I can feel it through the steering.

Any ideas?

Prob compression rod ball joint

When you installed the sway bar set did that include new end links? or was yours still in good condition it could be that

It didn't include new endlinks, but I had a shop install the front one for me. I would think they would have let me know if the front ones were shot...

Are you lowered? Even though you replaced the shocks you could possibly have a blown one. Usually the bushing inserts end up making a creaking sound...not so much a rattle...at least not that I have experienced. Not sure about the G35's though

No i'm not lowered. And this was happening before I had my shocks and struts replaced, and the sound didn't really change.

sounds like your passenger compression rod or the lower control arm bushings.

+1 for checking LCA.
