04 LS430 started making this noise as of late girlfriend pointed it out to me havent had the chance to get underneath to check anyone familiar with this noise 234k on the clock sounds like a tic on the passenger side no other issues than this drives smooth no limp mode or anything any help would be appreciated included a video had to convert to a zip to get it to fit unless someone knows another way to post it

 

I just saw your post in the other thread. I have the same noise, and have had it for almost the past 40k miles. No problems with the car. Had 2 dealers look/listen to it, along with 2 personal mechanics I know, and they all said to just drive the car. The dealers didn't want to guess what the noise was, or want to take the time (money on diagnosing) to figure it out. My mechanics both mentioned most likely a small leak on the passenger side, and depending on temperature and run time of the car the sound get noisier/quieter which would make sense with metal contracting and expanding. I added a link to my video I did 5 or so years ago. I had my phone sitting right on the fuse box when I started the car and then gave it some gas.

 

I appreciate your response man i heard the noise and instantly thought something was wrong

 

I thought the same thing with mine, as it appeared after having service done to the car. I have had absolutely no problems since.
