I have been plagued with a noisy front suspension on my 03 coupe for the last 6 months. When driving at slow speeds over bumps on the road there was a horrible popping rattling sound. I believe it stared because the roads here are so bad, tons of potholes everywhere. I took the car into the dealer and they told me it was my compression rods. They quoted me $900 to replace them. I decided to buy the parts for $295 shipped and replace them myself. It took 4 days to get the old compression rods off to replace the new ones. It was well worth the effort at the time because it solved my rattling problem.

About 2 weeks later I decided that I needed to buy 350z Tein H-Tech springs to lower the car. Now that I replaced the springs the same danm poping rattling sound is back. Son of a bitch! After doing some reading on the forums and finding out a lot of people had a similar problem because of bad end links. After reading that I remembered that while taking off the driverside endlink to replace the springs I noticed that the end link bolt that connects to the lower arm had spun when I tried to remove it. So I ordered SPL end links and installed them yesterday. I followed all the directions that SPL provided to set them up correctly.

I took the car for a ride after I was finished only to find that the sound is still there.

I dont know what to do next. Is it possiable that the driverside compression rod is already bad? please help!

do you run sway bars?

 

Might want to check your shocks. Mine made that noise when my shock went bad. Noise free after some d-specs.
