Weird squeak after Wavetrac install
Hi All,
Hoping you can help me with an annoying chirping/squeaking developed after I recently had a Wavetrac unit installed. Please see the video in the link below(well its really just audio). I had the car on jack stands and in 1st, accelerated to 10-15 mph and let off the gas, and.... SQUEAK. This seems to happen intermittently every 30 seconds or so while driving for the first 5-10 minutes of driving and then will go away again until everything is cold again. I thought it was a suspension bushing or something but this is doing it on jackstands with no movement in the subframe or real load on the drive line. Now I am starting to think U-joint or an axel seal? https://drive.google.com/file/d/1L6H...ew?usp=sharing |

wtf?? I was expecting like a high pitched squeak or something, not a saxophone noise!
I have no clue man, but it doesn't sound suspension related...

I have to say LOL @ this also. Totally unexpected noise. Can you place the camera in different positions and repeat the test to narrow down exactly where its coming from?
Also, have you went through the break-in procedure yet and changed the fluid? |

Could it be your exhaust flap maybe?? It opens briefly when letting off the gas like you described. Of course, it also opens in other situations, so if the noise is ONLY when you left off the gas, then that would rule the flap out.

Since it wasn't an immediate problem, in my mind this is another sign it could go away with the fluid change. You could have a lot of material built up in there from the break in.

Car is back at the shop today so hopefully we'll have the mysterious clown fart diagnosis shortly.
While highly entertaining, I am looking forward to this being resolved . |

New mounts fixed it!
Went with the turner delrin/aluminum mounts and WOW they are LOUD. They are awesome and handling is improved and i really like them. However with the delrin subframe bushings and diff bushings it definitely sounds like i am in a race car. These are not for those who a sensitive to nvh. |
