^Thats a possibility, but my 3rd brake light is on the trunk and I still have this problem.

 

Same here. I definitely know that the sound is coming from the bottom of the car. Because I can hear it better when my windows are down. Hopefully this weekend I can take out the sway bar. I finally got all the tools that will help me take it off.

 

im gonna put my eggs in the endlink basket. i didnt get the noise until a few days after i installed the hotchkis bars. i replaced the front endlinks but not the rear. i did read that some shock setups the hole is too big for the bolt and the strut actually bangs against the bolt during travel.

i have checked all the bolts and re-torqued them . still getting the noise i doubt one zeal strut took a crap after installing the sways.

 

There is a TSB for the squeak / creak coming from the rear seat area...

Remove the seats, and tighten a few bolts.. Done.

 

So here's an update. I tried once again to take the sway bar off. I had all the right tools, but I didn't have enough room to turn the breaker bar enough to loosen the nut. **** me off. So I went out and bought an electric impact wrench. I will try tomorrow or Saturday.

 

Which nut? The end links will come off using 2 wrenches. If you have an extension, the other 4 nuts should not be a problem. Use WD-40 if you have to.

 

Finally success! Also I just realized it has been 1 year since I started this thread. The nut was seized like a ****. My impact wrench can do 450 ft. lbs of torque but it still wouldn't budge. I then tried the passenger side and it came off quick. So I had some hope. I then tried again for the driver side, and still no go. I decide to do it by hand and use a ratchet to turn it (since the breaker bar was too long to turn). I applied a lot of force and was able to turn it.

I finally got the sway bar out. I then drove around for sometime and I didn't hear any knocking! I could always hear it when I pulled in/out of my driveway.

To other people who are having this problem, try taking the sway bar out. Hopefully your swaybar nuts aren't seized like mine so it should be a quick job for you.

So does this mean that I need to get new endlinks?

 

I began hearing this sound a couple of months ago. It would happen at random times with random space between days although now it seems more like once or twice during each drive. There doesn't seem to be anything wrong with performance.

I'm interested to see what the end diagnosis might be.

 

same here, my mechanic said its the strut bar brace

 

I just had my emissions and safety test done today.

I had the exact same noise you are describing, it turns out the "shield" around the exhaust was loose, he fixed it up for free, and now no noise!

 

I'm probably going to order some endlinks. I want to put they swaybar back in. Should I stick with OEM or get after-market?

 

I have a 2004 G35 coupe and I was experiencing the same problem with mine... It would happen at random intervals and only noticeable at slow speeds. Sounded like metal clanking.

After doing a lot of trouble shooting we found that the TPMS in the passenger rear tire had somehow come off the rim and was rolling around in the tire causing the noise. I cant speak for everyone but this was the cause of the sound that was in my car. Hope this helps!

 

....Wow, it came back, so I guess I'll be checking/replacing my endlinks also. I was so damn certain about the source of the sound, especially after it went away.
